Package 'reproducible'

Description

This package aims at making high-level, robust, machine and OS independent tools for making deeply reproducible and reusable content in R. The core user functions are Cache and prepInputs. Each of these is built around many core and edge cases required to have reproducible code of arbitrary complexity.

Main Tools

There are many elements within the reproducible package. However, there are currently two main ones that are critical for reproducible research. The key element for reproducible research is that the code must always return the same content every time it is run, but it must be vastly faster the 2nd, 3rd, 4th etc, time it is run. That way, the entire code sequence for a project of arbitrary size can be run from the start every time.

Cache():

A robust wrapper for any function, including those with environments, disk-backed storage (currently on Raster) class), operating-system independent, whose first time called will execute the function, second time will compare the inputs to a database of entries, and recover the first result if inputs are identical. If options("reproducible.useMemoise" = TRUE), the second time will be very fast as it will recover the answer from RAM.

prepInputs()for other specifics for other classes.:

Download, or load objects, and possibly post-process them. The main advantage to using this over more direct routes is that it will automatically build checksums tables, use Cache internally where helpful, and possibly run a variety of post-processing actions. This means this function can also itself be cached for even more speed. This allows all project data to be stored in custom cloud locations or in their original online data repositories, ⁠without altering code⁠ between the first, second, third, etc., times the code is run.

Description

This will first try to file.rename, and if that fails, then it will file.copy then file.remove.

Usage

.file.move(from, to, overwrite = FALSE)

Arguments

Value

Logical indicating whether operation succeeded.

Description

Intended for internal use. Exported so other packages can use this function.

Usage

.isMemoised(cacheId, cachePath = getOption("reproducible.cachePath"))

Arguments

Value

A logical, length 1 indicating whether the cacheId is memoised.

Description

Prepend (or postpend) a filename with a prefix (or suffix). If the directory name of the file cannot be ascertained from its path, it is assumed to be in the current working directory.

Usage

.prefix(f, prefix = "")

.suffix(f, suffix = "")

Arguments

Value

A character string or vector with the prefix pre-pended or suffix post-pended on the basename of the f, before the file extension.

Examples

# file's full path is specified (i.e., dirname is known)
myFile <- file.path("~/data", "file.tif")
.prefix(myFile, "small_") ## "/home/username/data/small_file.tif"
.suffix(myFile, "_cropped") ## "/home/username/data/myFile_cropped.shp"

# file's full path is not specified
.prefix("myFile.shp", "small") ## "./small_myFile.shp"
.suffix("myFile.shp", "_cropped") ## "./myFile_cropped.shp"

Description

Rasters are sometimes file-based, so the normal save and copy and assign mechanisms in R don't work for saving, copying and assigning. This function creates an explicit file copy of the file that is backing the raster, and changes the pointer (i.e., filename(object)) so that it is pointing to the new file.

Usage

.prepareFileBackedRaster(
  obj,
  repoDir = NULL,
  overwrite = FALSE,
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL),
  ...
)

Arguments

Value

A raster object and its newly located file backing. Note that if this is a legitimate Cache repository, the new location will be a subdirectory called ‘rasters/’ of ‘repoDir/’. If this is not a repository, the new location will be within repoDir.

Description

Remove attributes that are highly varying

Usage

.removeCacheAtts(x)

Arguments

Description

This provides a standard message format for missing packages, e.g., detected via requireNamespace.

Usage

.requireNamespace(
  pkg = "methods",
  minVersion = NULL,
  stopOnFALSE = FALSE,
  messageStart = NULL
)

Arguments

Value

A logical or stop if the namespace is not available to be loaded.

Description

Sets only a single element within a list attribute.

Usage

.setSubAttrInList(object, attr, subAttr, value)

Arguments

Value

This sets or updates the subAttr element of a list that is located at attr(object, attr), with the value. This, therefore, updates a sub-element of a list attribute and returns that same object with the updated attribute.

Description

This generic and some methods will do whatever is required to prepare an object for saving to disk (or RAM) via e.g., saveRDS. Some objects (e.g., terra's ⁠Spat*⁠) cannot be saved without first wrapping them. Also, file-backed objects are similar.

.wrap(
  obj,
  cachePath,
  preDigest,
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL),
  verbose = getOption("reproducible.verbose"),
  outputObjects = NULL,
  ...
)

Description

A version of base::basename that is NULL resistant

Usage

basename2(x)

Arguments

Value

NULL if x is NULL, otherwise, as basename.

Same as base::basename()

Description

A function that can be used to wrap around other functions to cache function calls for later use. This is normally most effective when the function to cache is slow to run, yet the inputs and outputs are small. The benefit of caching, therefore, will decline when the computational time of the "first" function call is fast and/or the argument values and return objects are large. The default setting (and first call to Cache) will always save to disk. The 2nd call to the same function will return from disk, unless options("reproducible.useMemoise" = TRUE), then the 2nd time will recover the object from RAM and is normally much faster (at the expense of RAM use).

Usage

Cache(
  FUN,
  ...,
  notOlderThan = NULL,
  .objects = NULL,
  .cacheExtra = NULL,
  .functionName = NULL,
  outputObjects = NULL,
  algo = "xxhash64",
  cacheRepo = NULL,
  cachePath = NULL,
  length = getOption("reproducible.length", Inf),
  compareRasterFileLength,
  userTags = c(),
  omitArgs = NULL,
  classOptions = list(),
  debugCache = character(),
  sideEffect = FALSE,
  makeCopy = FALSE,
  quick = getOption("reproducible.quick", FALSE),
  verbose = getOption("reproducible.verbose", 1),
  cacheId = NULL,
  useCache = getOption("reproducible.useCache", TRUE),
  useCloud = FALSE,
  cloudFolderID = NULL,
  showSimilar = getOption("reproducible.showSimilar", FALSE),
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL)
)

Arguments

Details

There are other similar functions in the R universe. This version of Cache has been used as part of a robust continuous workflow approach. As a result, we have tested it with many "non-standard" R objects (e.g., RasterLayer, ⁠Spat*⁠ objects) and environments (which are always unique, so do not cache readily).

This version of the Cache function accommodates those four special, though quite common, cases by:

1. converting any environments into list equivalents;

2. identifying the dispatched S4 method (including those made through inheritance) before hashing so the correct method is being cached;

3. by hashing the linked file, rather than the raster object. Currently, only file-backed ⁠Raster*⁠ or ⁠Spat*⁠ objects are digested (e.g., not ff objects, or any other R object where the data are on disk instead of in RAM);

4. Uses digest::digest() This is used for file-backed objects as well.

5. Cache will save arguments passed by user in a hidden environment. Any nested Cache functions will use arguments in this order: 1) actual arguments passed at each Cache call; 2) any inherited arguments from an outer Cache call; 3) the default values of the Cache function. See section on Nested Caching.

Cache will add a tag to the entry in the cache database called accessed, which will assign the time that it was accessed, either read or write. That way, cached items can be shown (using showCache) or removed (using clearCache) selectively, based on their access dates, rather than only by their creation dates. See example in clearCache().

Value

Returns the value of the function call or the cached version (i.e., the result from a previous call to this same cached function with identical arguments).

Nested Caching

Commonly, Caching is nested, i.e., an outer function is wrapped in a Cache function call, and one or more inner functions are also wrapped in a Cache function call. A user can always specify arguments in every Cache function call, but this can get tedious and can be prone to errors. The normal way that R handles arguments is it takes the user passed arguments if any, and default arguments for all those that have no user passed arguments. We have inserted a middle step. The order or precedence for any given Cache function call is

1. user arguments, 2. inherited arguments, 3. default arguments. At this time, the top level Cache arguments will propagate to all inner functions unless each individual Cache call has other arguments specified, i.e., "middle" nested Cache function calls don't propagate their arguments to further "inner" Cache function calls. See example.

userTags is unique of all arguments: its values will be appended to the inherited userTags.

quick

The quick argument is attempting to sort out an ambiguity with character strings: are they file paths or are they simply character strings. When quick = TRUE, Cache will treat these as character strings; when quick = FALSE, they will be attempted to be treated as file paths first; if there is no file, then it will revert to treating them as character strings. If user passes a character vector to this, then this will behave like omitArgs: quick = "file" will treat the argument "file" as character string.

The most often encountered situation where this ambiguity matters is in arguments about filenames: is the filename an input pointing to an object whose content we want to assess (e.g., a file-backed raster), or an output (as in saveRDS) and it should not be assessed. If only run once, the output file won't exist, so it will be treated as a character string. However, once the function has been run once, the output file will exist, and Cache(...) will assess it, which is incorrect. In these cases, the user is advised to use quick = "TheOutputFilenameArgument" to specify the argument whose content on disk should not be assessed, but whose character string should be assessed (distinguishing it from omitArgs = "TheOutputFilenameArgument", which will not assess the file content nor the character string).

This is relevant for objects of class character, Path and Raster currently. For class character, it is ambiguous whether this represents a character string or a vector of file paths. If it is known that character strings should not be treated as paths, then quick = TRUE is appropriate, with no loss of information. If it is file or directory, then it will digest the file content, or basename(object). For class Path objects, the file's metadata (i.e., filename and file size) will be hashed instead of the file contents if quick = TRUE. If set to FALSE (default), the contents of the file(s) are hashed. If quick = TRUE, length is ignored. Raster objects are treated as paths, if they are file-backed.

Caching Speed

Caching speed may become a critical aspect of a final product. For example, if the final product is a shiny app, rerunning the entire project may need to take less then a few seconds at most. There are 3 arguments that affect Cache speed: quick, length, and algo. quick is passed to .robustDigest, which currently only affects Path and ⁠Raster*⁠ class objects. In both cases, quick means that little or no disk-based information will be assessed.

Filepaths

If a function has a path argument, there is some ambiguity about what should be done. Possibilities include:

1. hash the string as is (this will be very system specific, meaning a Cache call will not work if copied between systems or directories);

2. hash the basename(path);

3. hash the contents of the file.

If paths are passed in as is (i.e,. character string), the result will not be predictable. Instead, one should use the wrapper function asPath(path), which sets the class of the string to a Path, and one should decide whether one wants to digest the content of the file (using quick = FALSE), or just the filename ((quick = TRUE)). See examples.

Stochasticity or randomness

In general, it is expected that caching will only be used when randomness is not desired, e.g., Cache(rnorm(1)) is unlikely to be useful in many cases. However, Cache captures the call that is passed to it, leaving all functions unevaluated. As a result Cache(glm, x ~ y, rnorm(1)) will not work as a means of forcing a new evaluation each time, as the rnorm(1) is not evaluated before the call is assessed against the cache database. To force a new call each time, evaluate the randomness prior to the Cache call, e.g., ran = rnorm(1) then pass this to .cacheExtra, e.g., Cache(glm, x ~ y, .cacheExtra = ran)

drv and conn

By default, drv uses an SQLite database. This can be sufficient for most cases. However, if a user has dozens or more cores making requests to the Cache database, it may be insufficient. A user can set up a different database backend, e.g., PostgreSQL that can handle multiple simultaneous read-write situations. See https://github.com/PredictiveEcology/SpaDES/wiki/Using-alternate-database-backends-for-Cache.

useCache

Logical or numeric. If FALSE or 0, then the entire Caching mechanism is bypassed and the function is evaluated as if it was not being Cached. Default is getOption("reproducible.useCache")), which is TRUE by default, meaning use the Cache mechanism. This may be useful to turn all Caching on or off in very complex scripts and nested functions. Increasing levels of numeric values will cause deeper levels of Caching to occur (though this may not work as expected in all cases). The following is no longer supported: Currently, only implemented in postProcess: to do both caching of inner cropInputs, projectInputs and maskInputs, and caching of outer postProcess, use useCache = 2; to skip the inner sequence of 3 functions, use useCache = 1. For large objects, this may prevent many duplicated save to disk events.

If useCache = "overwrite" (which can be set with options("reproducible.useCache" = "overwrite")), then the function invoke the caching mechanism but will purge any entry that is matched, and it will be replaced with the results of the current call.

If useCache = "devMode": The point of this mode is to facilitate using the Cache when functions and datasets are continually in flux, and old Cache entries are likely stale very often. In devMode, the cache mechanism will work as normal if the Cache call is the first time for a function OR if it successfully finds a copy in the cache based on the normal Cache mechanism. It differs from the normal Cache if the Cache call does not find a copy in the cachePath, but it does find an entry that matches based on userTags. In this case, it will delete the old entry in the cachePath (identified based on matching userTags), then continue with normal Cache. For this to work correctly, userTags must be unique for each function call. This should be used with caution as it is still experimental. Currently, if userTags are not unique to a single entry in the cachePath, it will default to the behaviour of useCache = TRUE with a message. This means that "devMode" is most useful if used from the start of a project.

useCloud

This is experimental and there are many conditions under which this is known to not work correctly. This is a way to store all or some of the local Cache in the cloud. Currently, the only cloud option is Google Drive, via googledrive. For this to work, the user must be or be able to be authenticated with googledrive::drive_auth. The principle behind this useCloud is that it will be a full or partial mirror of a local Cache. It is not intended to be used independently from a local Cache. To share objects that are in the Cloud with another person, it requires 2 steps. 1) share the cloudFolderID$id, which can be retrieved by getOption("reproducible.cloudFolderID")$id after at least one Cache call has been made. 2) The other user must then set their cacheFolderID in a ⁠Cache\(..., reproducible.cloudFolderID = \"the ID here\"\)⁠ call or set their option manually ⁠options\(\"reproducible.cloudFolderID\" = \"the ID here\"\)⁠.

If TRUE, then this Cache call will download (if local copy doesn't exist, but cloud copy does exist), upload (local copy does or doesn't exist and cloud copy doesn't exist), or will not download nor upload if object exists in both. If TRUE will be at least 1 second slower than setting this to FALSE, and likely even slower as the cloud folder gets large. If a user wishes to keep "high-level" control, set this to getOption("reproducible.useCloud", FALSE) or getOption("reproducible.useCloud", TRUE) (if the default behaviour should be FALSE or TRUE, respectively) so it can be turned on and off with this option. NOTE: This argument will not be passed into inner/nested Cache calls.)

Object attributes

Users should be cautioned that object attributes may not be preserved, especially in the case of objects that are file-backed, such as Raster or SpatRaster objects. If a user needs to keep attributes, they may need to manually re-attach them to the object after recovery. With the example of SpatRaster objects, saving to disk requires terra::wrap if it is a memory-backed object. When running terra::unwrap on this object, any attributes that a user had added are lost.

sideEffect

This feature is now deprecated. Do not use as it is ignored.

Note

As indicated above, several objects require pre-treatment before caching will work as expected. The function .robustDigest accommodates this. It is an S4 generic, meaning that developers can produce their own methods for different classes of objects. Currently, there are methods for several types of classes. See .robustDigest().

Description

This can be used by a user to pre-test their arguments before running Cache, for example to determine whether there is a cached copy.

Usage

CacheDigest(
  objsToDigest,
  ...,
  algo = "xxhash64",
  calledFrom = "CacheDigest",
  .functionName = NULL,
  quick = FALSE
)

Arguments

Value

A list of length 2 with the outputHash, which is the digest that Cache uses for cacheId and also preDigest, which is the digest of each sub-element in objsToDigest.

Examples

data.table::setDTthreads(2)
a <- Cache(rnorm, 1)

# like with Cache, user can pass function and args in a few ways
CacheDigest(rnorm(1)) # shows same cacheId as previous line
CacheDigest(rnorm, 1) # shows same cacheId as previous line

Description

Usage

CacheGeo(
  targetFile = NULL,
  url = NULL,
  domain,
  FUN,
  destinationPath = getOption("reproducible.destinationPath", "."),
  useCloud = getOption("reproducible.useCloud", FALSE),
  cloudFolderID = NULL,
  purge = FALSE,
  useCache = getOption("reproducible.useCache"),
  overwrite = getOption("reproducible.overwrite"),
  action = c("nothing", "update", "replace", "append"),
  ...
)

Arguments

Details

This function is a combination of Cache and prepInputs but for spatial domains. This differs from Cache in that the current function call doesn't have to have an identical function call previously run. Instead, it needs to have had a previous function call where the domain being passes is within the geographic limits of the targetFile or file located at the url. This is similar to a geospatial operation on a remote GIS server, with 2 differences:

1. This downloads the object first before doing the GIS locally, and 2. it will optionally upload an updated object if the geographic area did not yet exist.

This has a very specific use case: assess whether an existing sf polygon or multipolygon object (local or remote) covers the spatial area of a domain of interest. If it does, then return only that part of the sf object that completely covers the domain. If it does not, then run FUN. It is expected that FUN will produce an sf polygon or multipolygon class object. The result of FUN will then be appended to the sf object as a new entry (feature) or it will replace the existing "same extent" entry in the sf object.

Value

Returns an object that results from FUN, which will possibly be a subset of a larger spatial object that is specified with targetFile or url.

Examples

if (requireNamespace("sf", quietly = TRUE) &&
    requireNamespace("terra", quietly = TRUE)) {
dPath <- checkPath(file.path(tempdir2()), create = TRUE)
localFileLux <- system.file("ex/lux.shp", package = "terra")

  # 1 step for each layer
  # 1st step -- get study area
  full <- prepInputs(localFileLux, destinationPath = dPath) # default is sf::st_read
  zoneA <- full[3:6, ]
  zoneB <- full[8, ] # not in A
  zoneC <- full[3, ] # yes in A
  zoneD <- full[7:8, ] # not in A, B or C
  zoneE <- full[3:5, ] # yes in A
  # 2nd step: re-write to disk as read/write is lossy; want all "from disk" for this ex.
  writeTo(zoneA, writeTo = "zoneA.shp", destinationPath = dPath)
  writeTo(zoneB, writeTo = "zoneB.shp", destinationPath = dPath)
  writeTo(zoneC, writeTo = "zoneC.shp", destinationPath = dPath)
  writeTo(zoneD, writeTo = "zoneD.shp", destinationPath = dPath)
  writeTo(zoneE, writeTo = "zoneE.shp", destinationPath = dPath)
  # Must re-read to get identical columns
  zoneA <- sf::st_read(file.path(dPath, "zoneA.shp"))
  zoneB <- sf::st_read(file.path(dPath, "zoneB.shp"))
  zoneC <- sf::st_read(file.path(dPath, "zoneC.shp"))
  zoneD <- sf::st_read(file.path(dPath, "zoneD.shp"))
  zoneE <- sf::st_read(file.path(dPath, "zoneE.shp"))

  # The function that is to be run. This example returns a data.frame because
  #    saving `sf` class objects with list-like columns does not work with
  #    many st_driver()
  fun <- function(domain, newField) {
    domain |>
      as.data.frame() |>
      cbind(params = I(lapply(seq_len(NROW(domain)), function(x) newField)))
  }

  # Run sequence -- A, B will add new entries in targetFile, C will not,
  #                 D will, E will not
  for (z in list(zoneA, zoneB, zoneC, zoneD, zoneE)) {
    out <- CacheGeo(
      targetFile = "fireSenseParams.rds",
      domain = z,
      FUN = fun(domain, newField = I(list(list(a = 1, b = 1:2, c = "D")))),
      fun = fun, # pass whatever is needed into the function
      destinationPath = dPath,
      action = "update"
      # , cloudFolderID = "cachedObjects" # to upload/download from cloud
    )
  }
}

Description

Will check for presence of a cloudFolderID and make a new one if one not present on Google Drive, with a warning.

Usage

checkAndMakeCloudFolderID(
  cloudFolderID = getOption("reproducible.cloudFolderID", NULL),
  cachePath = NULL,
  create = FALSE,
  overwrite = FALSE,
  verbose = getOption("reproducible.verbose", 1),
  team_drive = NULL
)

Arguments

Value

Returns the character string of the cloud folder ID created or reported

Description

Checks the specified path to a directory for formatting consistencies, such as trailing slashes, etc.

Usage

checkPath(path, create)

## S4 method for signature 'character,logical'
checkPath(path, create)

## S4 method for signature 'character,missing'
checkPath(path)

## S4 method for signature 'NULL,ANY'
checkPath(path)

## S4 method for signature 'missing,ANY'
checkPath()

Arguments

Value

Character string denoting the cleaned up filepath.

Note

This will not work for paths to files. To check for existence of files, use file.exists(). To normalize a path to a file, use normPath() or normalizePath().

See Also

file.exists(), dir.create(), normPath()

Examples

## normalize file paths
paths <- list("./aaa/zzz",
              "./aaa/zzz/",
              ".//aaa//zzz",
              ".//aaa//zzz/",
              ".\\\\aaa\\\\zzz",
              ".\\\\aaa\\\\zzz\\\\",
              file.path(".", "aaa", "zzz"))

checked <- normPath(paths)
length(unique(checked)) ## 1; all of the above are equivalent

## check to see if a path exists
tmpdir <- file.path(tempdir(), "example_checkPath")

dir.exists(tmpdir) ## FALSE
tryCatch(checkPath(tmpdir, create = FALSE), error = function(e) FALSE) ## FALSE

checkPath(tmpdir, create = TRUE)
dir.exists(tmpdir) ## TRUE

unlink(tmpdir, recursive = TRUE)

Description

This confirms that the files which may be absolute actually exist when compared makeRelative(knownRelativeFiles, absolutePrefix). This is different than just using basename because it will include any sub-folder structure within the knownRelativePaths

Usage

checkRelative(
  files,
  absolutePrefix,
  knownRelativeFiles,
  verbose = getOption("reproducible.verbose")
)

Arguments

Description

Verify (and optionally write) checksums. Checksums are computed using .digest(), which is simply a wrapper around digest::digest.

Usage

Checksums(
  path,
  write,
  quickCheck = getOption("reproducible.quickCheck", FALSE),
  checksumFile = identifyCHECKSUMStxtFile(path),
  files = NULL,
  verbose = getOption("reproducible.verbose", 1),
  ...
)

## S4 method for signature 'character,logical'
Checksums(
  path,
  write,
  quickCheck = getOption("reproducible.quickCheck", FALSE),
  checksumFile = identifyCHECKSUMStxtFile(path),
  files = NULL,
  verbose = getOption("reproducible.verbose", 1),
  ...
)

## S4 method for signature 'character,missing'
Checksums(
  path,
  write,
  quickCheck = getOption("reproducible.quickCheck", FALSE),
  checksumFile = identifyCHECKSUMStxtFile(path),
  files = NULL,
  verbose = getOption("reproducible.verbose", 1),
  ...
)

Arguments

Value

A data.table with columns: result, expectedFile, actualFile, checksum.x, checksum.y, algorithm.x, algorithm.y, filesize.x, filesize.y indicating the result of comparison between local file (x) and expectation based on the CHECKSUMS.txt file.

Note

In version 1.2.0 and earlier, two checksums per file were required because of differences in the checksum hash values on Windows and Unix-like platforms. Recent versions use a different (faster) algorithm and only require one checksum value per file. To update your ‘CHECKSUMS.txt’ files using the new algorithm, see https://github.com/PredictiveEcology/SpaDES/issues/295#issuecomment-246513405.

Examples

## Not run: 
modulePath <- file.path(tempdir(), "myModulePath")
dir.create(modulePath, recursive = TRUE, showWarnings = FALSE)
moduleName <- "myModule"
cat("hi", file = file.path(modulePath, moduleName)) # put something there for this example

## verify checksums of all data files
Checksums(modulePath, files = moduleName)

## write new CHECKSUMS.txt file
Checksums(files = moduleName, modulePath, write = TRUE)

## End(Not run)

Description

Meant for internal use, as there are internal objects as arguments.

Usage

cloudDownload(
  outputHash,
  newFileName,
  gdriveLs,
  cachePath,
  cloudFolderID,
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL),
  verbose = getOption("reproducible.verbose")
)

Arguments

Description

Copied from http://www.cookbook-r.com/Manipulating_data/Comparing_vectors_or_factors_with_NA/. This function returns TRUE wherever elements are the same, including NA's, and FALSE everywhere else.

Usage

compareNA(v1, v2)

Arguments

Value

A logical vector, indicating positions where two vectors are same or differ.

Examples

a <- c(NA, 1, 2, NA)
b <- c(1, NA, 2, NA)
compareNA(a, b)

Description

convertPaths is simply a wrapper around gsub for changing the first part of a path. convertRasterPaths is useful for changing the path to a file-backed raster (e.g., after copying the file to a new location).

Usage

convertPaths(x, patterns, replacements)

convertRasterPaths(x, patterns, replacements)

Arguments

Value

A normalized path with the patterns replaced by replacements. Or a list of such objects if x was a list.

Examples

filenames <- c("/home/user1/Documents/file.txt", "/Users/user1/Documents/file.txt")
oldPaths <- dirname(filenames)
newPaths <- c("/home/user2/Desktop", "/Users/user2/Desktop")
convertPaths(filenames, oldPaths, newPaths)

Description

When copying environments and all the objects contained within them, there are no copies made: it is a pass-by-reference operation. Sometimes, a deep copy is needed, and sometimes, this must be recursive (i.e., environments inside environments).

Usage

Copy(object, ...)

## S4 method for signature 'ANY'
Copy(
  object,
  filebackedDir,
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL),
  verbose = getOption("reproducible.verbose"),
  ...
)

## S4 method for signature 'data.table'
Copy(object, ...)

## S4 method for signature 'list'
Copy(object, ...)

## S4 method for signature 'refClass'
Copy(object, ...)

## S4 method for signature 'data.frame'
Copy(object, ...)

Arguments

Details

To create a new Copy method for a class that needs its own method, try something like shown in example and put it in your package (or other R structure).

Value

The same object as object, but with pass-by-reference class elements "deep" copied. reproducible has methods for several classes.

e$one <- 1L
e$lst <- list(W = 1:10, X = runif(10), Y = rnorm(10), Z = LETTERS[1:10])
ls(e)

# 'normal' copy
f <- e
ls(f)
f$one
f$one <- 2L
f$one
e$one ## uh oh, e has changed!

# deep copy
e$one <- 1L
g <- Copy(e)
ls(g)
g$one
g$one <- 3L
g$one
f$one
e$one
## To create a new deep copy method, use the following template
## setMethod("Copy", signature = "the class", # where = specify here if not in a package,
##           definition = function(object, filebackendDir, ...) {
##           # write deep copy code here
##           })

Description

This is replacement for file.copy, but for one file at a time. The additional feature is that it will use robocopy (on Windows) or rsync on Linux or Mac, if they exist. It will default back to file.copy if none of these exists. If there is a possibility that the file already exists, then this function should be very fast as it will do "update only", i.e., nothing.

Usage

copySingleFile(
  from = NULL,
  to = NULL,
  useRobocopy = TRUE,
  overwrite = TRUE,
  delDestination = FALSE,
  create = TRUE,
  silent = FALSE
)

copyFile(
  from = NULL,
  to = NULL,
  useRobocopy = TRUE,
  overwrite = TRUE,
  delDestination = FALSE,
  create = TRUE,
  silent = FALSE
)

Arguments

Value

This function is called for its side effect, i.e., a file is copied from to to.

Description

Determine the filename, given various combinations of inputs.

Usage

determineFilename(
  filename2 = NULL,
  filename1 = NULL,
  destinationPath = getOption("reproducible.destinationPath", "."),
  verbose = getOption("reproducible.verbose", 1),
  prefix = "Small",
  ...
)

Arguments

Details

The post processing workflow, which includes this function, addresses several scenarios, and depending on which scenario, there are several file names at play. For example, Raster objects may have file-backed data, and so possess a file name, whereas Spatial objects do not. Also, if post processing is part of a prepInputs() workflow, there will always be a file downloaded. From the perspective of postProcess, these are the "inputs" or filename1. Similarly, there may or may not be a desire to write an object to disk after all post processing, filename2.

This subtlety means that there are two file names that may be at play: the "input" file name (filename1), and the "output" filename (filename2). When this is used within postProcess, it is straight forward.

However, when postProcess is used within a prepInputs call, the filename1 file is the file name of the downloaded file (usually automatically known following the downloading, and refered to as targetFile) and the filename2 is the file name of the of post-processed file.

If filename2 is TRUE, i.e., not an actual file name, then the cropped/masked raster will be written to disk with the original filenam1/targetFile name, with prefix prefixed to the basename(targetFile).

If filename2 is a character string, it will be the path of the saved/written object e.g., passed to writeOutput. It will be tested whether it is an absolute or relative path and used as is if absolute or prepended with destinationPath if relative.

If filename2 is logical, then the output filename will be prefix prefixed to the basename(filename1). If a character string, it will be the path returned. It will be tested whether it is an absolute or relative path and used as is if absolute or prepended with destinationPath if provided, and if filename2 is relative.

Details

These three functions are used within postProcessTo, in the sequence: gdalProject, gdalResample and gdalMask, when from and projectTo are SpatRaster and maskTo is a SpatVector, but only if options(reproducible.gdalwarp = TRUE) is set.

This sequence is a slightly different order than the sequence when gdalwarp = FALSE or the arguments do not match the above. This sequence was determined to be faster and more accurate than any other sequence, including running all three steps in one gdalwarp call (which gdalwarp can do). Using one-step gdalwarp resulted in very coarse pixelation when converting from a coarse resolution to fine resolution, which visually was inappropriate in test cases.

Description

Extracting relative file paths.

Usage

getRelative(path, relativeToPath)

makeRelative(files, absoluteBase)

Arguments

Details

• getRelative() searches path "from the right" (instead of "from the left") and tries to reconstruct it relative to directory specified by relativeToPath. This is useful when dealing with symlinked paths.

• makeRelative() checks to see if files and normPath(absoluteBase) share a common path (i.e., "from the left"), otherwise it returns files.

Examples

## create a project directory (e.g., on a hard drive)
(tmp1 <- tempdir2("myProject", create = TRUE))

## create a cache directory elsewhere (e.g., on an SSD)
(tmp2 <- tempdir2("my_cache", create = TRUE))

## symlink the project cache directory to tmp2
## files created here are actually stored in tmp2
prjCache <- file.path(tmp1, "cache")
file.symlink(tmp2, prjCache)

## create a dummy cache object file in the project cache dir
(tmpf <- tempfile("cache_", prjCache))
cat(rnorm(100), file = tmpf)
file.exists(tmpf)
normPath(tmpf) ## note the 'real' location (i.e., symlink resolved)

getRelative(tmpf, prjCache) ## relative path
getRelative(tmpf, tmp2) ## relative path

makeRelative(tmpf, tmp2) ## abs path; tmpf and normPath(tmp2) don't share common path
makeRelative(tmpf, prjCache) ## abs path; tmpf and normPath(tmp2) don't share common path
makeRelative(normPath(tmpf), prjCache) ## rel path; share common path when both normPath-ed

unlink(tmp1, recursive = TRUE)
unlink(tmp2, recursive = TRUE)

Checks for existed of a url or the internet using https://CRAN.R-project.org

Description

A lightweight function that may be less reliable than more purpose built solutions such as checking a specific web page using RCurl::url.exists. However, this is slightly faster and is sufficient for many uses.

Usage

internetExists()

urlExists(url)

Arguments

Value

Logical, TRUE if internet site exists, FALSE otherwise

Logical, TRUE if internet site exists, FALSE otherwise.

Description

Has a cached object has been updated?

Usage

isUpdated(x)

Arguments

Value

logical

Description

When intersections occur, what was originally 2 polygons features can become LINESTRING and/or POINT and any COLLECTIONS or ⁠MULTI-⁠ versions of these. This function evaluates what the original geometry was and drops any newly created different geometries. For example, if a POLYGON becomes a COLLECTION of MULTIPOLYGON, POLYGON and POINT geometries, the POINT geometries will be dropped. This function is used internally in postProcessTo().

Usage

keepOrigGeom(newObj, origObj)

Arguments

Value

The original newObj, but with only the type of geometry that entered into the function.

Description

Attempt first to make a hardlink. If that fails, try to make a symlink (on non-windows systems and symlink = TRUE). If that fails, copy the file.

Usage

linkOrCopy(
  from,
  to,
  symlink = TRUE,
  overwrite = TRUE,
  verbose = getOption("reproducible.verbose", 1)
)

Arguments

Value

This function is called for its side effects, which will be a file.link is that is available or file.copy if not (e.g., the two directories are not on the same physical disk).

Note

Use caution with files-backed objects (e.g., rasters). See examples.

  isTRUE(all.equal(r3a, r4a)) # TRUE

  ## cleanup
  unlink(tmpDir, recursive = TRUE)
}

Description

This is a convenience wrapper around ⁠newList <- list(a = 1); names(newList) <- "a"⁠.

Usage

listNamed(...)

Arguments

Details

This will return a named list, where names are the object names, captured internally in the function and assigned to the list. If a user manually supplies names, these will be kept (i.e., not overwritten by the object name).

Examples

a <- 1
b <- 2
d <- 3
(newList <- listNamed(a, b, dManual = d)) # "dManual" name kept

Description

Load a file from the cache

Usage

loadFile(file, format = NULL)

Arguments

Value

the object loaded from file

Description

Usage

mergeCache(
  cacheTo,
  cacheFrom,
  drvTo = getDrv(getOption("reproducible.drv", NULL)),
  drvFrom = getDrv(getOption("reproducible.drv", NULL)),
  connTo = NULL,
  connFrom = NULL,
  verbose = getOption("reproducible.verbose")
)

## S4 method for signature 'ANY'
mergeCache(
  cacheTo,
  cacheFrom,
  drvTo = getDrv(getOption("reproducible.drv", NULL)),
  drvFrom = getDrv(getOption("reproducible.drv", NULL)),
  connTo = NULL,
  connFrom = NULL,
  verbose = getOption("reproducible.verbose")
)

Arguments

Details

All the cacheFrom artifacts will be put into cacheTo repository. All userTags will be copied verbatim, including accessed, with 1 exception: date will be the current Sys.time() at the time of merging. The createdDate column will be similarly the current time of merging.

Value

The character string of the path of cacheTo, i.e., not the objects themselves.

Description

This family has a consistent use of verbose allowing messages to be turned on or off or verbosity increased or decreased throughout the family of messaging in reproducible.

Usage

messageDF(
  df,
  round,
  colour = NULL,
  colnames = NULL,
  indent = NULL,
  verbose = getOption("reproducible.verbose"),
  verboseLevel = 1,
  appendLF = TRUE
)

messagePrepInputs(
  ...,
  appendLF = TRUE,
  verbose = getOption("reproducible.verbose"),
  verboseLevel = 1
)

messagePreProcess(
  ...,
  appendLF = TRUE,
  verbose = getOption("reproducible.verbose"),
  verboseLevel = 1
)

messageCache(
  ...,
  colour = getOption("reproducible.messageColourCache"),
  verbose = getOption("reproducible.verbose"),
  verboseLevel = 1,
  appendLF = TRUE
)

messageQuestion(..., verboseLevel = 0, appendLF = TRUE)

.messageFunctionFn(
  ...,
  appendLF = TRUE,
  verbose = getOption("reproducible.verbose"),
  verboseLevel = 1
)

messageColoured(
  ...,
  colour = NULL,
  indent = NULL,
  hangingIndent = TRUE,
  verbose = getOption("reproducible.verbose", 1),
  verboseLevel = 1,
  appendLF = TRUE
)

Arguments

Details

• messageDF uses message to print a clean square data structure.

• messageColoured allows specific colours to be used.

• messageQuestion sets a high level for verbose so that the message always gets asked.

Value

Used for side effects. This will produce a message of a structured data.frame.

Description

During the transition from raster to terra, some functions are not drop in replacements, such as minValue and maxValue became terra::minmax. This helper allows one function to be used, which calls the correct max or min function, depending on whether the object is a Raster or SpatRaster.

Usage

minFn(x)

maxFn(x)

dataType2(x, ...)

nlayers2(x)

values2(x, ...)

Arguments

Value

A vector (not matrix as in terra::minmax) with the minimum or maximum value on the Raster or SpatRaster, one value per layer.

Examples

if (requireNamespace("terra", quietly = TRUE)) {
  ras <- terra::rast(terra::ext(0, 10, 0, 10), vals = 1:100)
  maxFn(ras)
  minFn(ras)
}

Description

If a user manually copies a complete Cache folder (including the db file and rasters folder), there are issues that must be addressed, depending on the Cache backend used. If using DBI (e.g., RSQLite or Postgres), the db table must be renamed. Run this function after a manual copy of a cache folder. See examples for one way to do that.

Usage

movedCache(
  new,
  old,
  drv = getDrv(getOption("reproducible.drv", NULL)),
  conn = getOption("reproducible.conn", NULL),
  verbose = getOption("reproducible.verbose")
)

Arguments

Details

When the backend database for a reproducinle cache is an SQL database, the files on disk cannot be copied manually to a new location because they contain internal tables. Because reproducible gives the main table a name based on the cachePath path, calls to Cache will attempt to call this internally if it detects a name mismatch.

Value

movedCache does not return anything; it is called for its side effects.

Examples

data.table::setDTthreads(2)
tmpdir <- "tmpdir"
tmpCache <- "tmpCache"
tmpCacheDir <- normalizePath(file.path(tempdir(), tmpCache), mustWork = FALSE)
tmpdirPath <- normalizePath(file.path(tempdir(), tmpdir), mustWork = FALSE)
bb <- Cache(rnorm, 1, cachePath = tmpCacheDir)

# Copy all files from tmpCache to tmpdir
froms <- normalizePath(dir(tmpCacheDir, recursive = TRUE, full.names = TRUE),
  mustWork = FALSE
)
dir.create(file.path(tmpdirPath, "rasters"), recursive = TRUE, showWarnings = FALSE)
dir.create(file.path(tmpdirPath, "cacheOutputs"), recursive = TRUE, showWarnings = FALSE)
file.copy(
  from = froms, overwrite = TRUE,
  to = gsub(tmpCache, tmpdir, froms)
)

# Can use 'movedCache' to update the database table, though will generally
#   happen automatically, with message indicating so
movedCache(new = tmpdirPath, old = tmpCacheDir)
bb <- Cache(rnorm, 1, cachePath = tmpdirPath) # should recover the previous call

Description

Checks the specified path for formatting consistencies:

1. use slash instead of backslash;

2. do tilde etc. expansion;

3. remove trailing slash.

Usage

normPath(path)

## S4 method for signature 'character'
normPath(path)

## S4 method for signature 'list'
normPath(path)

## S4 method for signature 'NULL'
normPath(path)

## S4 method for signature 'missing'
normPath()

## S4 method for signature 'logical'
normPath(path)

normPathRel(path)

Arguments

Details

Additionally, normPath() attempts to create a absolute paths, whereas normPathRel() maintains relative paths.

d> getwd()
[1] "/home/achubaty/Documents/GitHub/PredictiveEcology/reproducible"
d> normPathRel("potato/chips")
[1] "potato/chips"
d> normPath("potato/chips")
[1] "/home/achubaty/Documents/GitHub/PredictiveEcology/reproducible/potato/chips"

Value

Character vector of cleaned up filepaths.

Examples

## normalize file paths
paths <- list("./aaa/zzz",
              "./aaa/zzz/",
              ".//aaa//zzz",
              ".//aaa//zzz/",
              ".\\\\aaa\\\\zzz",
              ".\\\\aaa\\\\zzz\\\\",
              file.path(".", "aaa", "zzz"))

checked <- normPath(paths)
length(unique(checked)) ## 1; all of the above are equivalent

## check to see if a path exists
tmpdir <- file.path(tempdir(), "example_checkPath")

dir.exists(tmpdir) ## FALSE
tryCatch(checkPath(tmpdir, create = FALSE), error = function(e) FALSE) ## FALSE

checkPath(tmpdir, create = TRUE)
dir.exists(tmpdir) ## TRUE

unlink(tmpdir, recursive = TRUE)

Description

This function attempts to estimate the real object size of an object. If the object has pass-by-reference semantics, it may not estimate the object size well without a specific method developed. For the case of terra class objects, this will be accurate (both RAM and file size), but only if it is not passed inside a list or environment. To get an accurate size of these, they should be passed individually.

Usage

objSize(x, quick = FALSE, ...)

objSizeSession(sumLevel = Inf, enclosingEnvs = TRUE, .prevEnvirs = list())

Arguments

Details

For functions, a user can include the enclosing environment as described https://www.r-bloggers.com/2015/03/using-closures-as-objects-in-r/ and http://adv-r.had.co.nz/memory.html. It is not entirely clear which estimate is better. However, if the enclosing environment is the .GlobalEnv, it will not be included even though enclosingEnvs = TRUE.

objSizeSession will give the size of the whole session, including loaded packages. Because of the difficulties in calculating the object size of base and methods packages and Autoloads, these are omitted.

Value

This will return the result from lobstr::obj_size, i.e., a lobstr_bytes which is a numeric. If quick = FALSE, it will also have an attribute, "objSize", which will be a list with each element being the objSize of the individual elements of x. This is particularly useful if x is a list or environment. However, because of the potential for shared memory, the sum of the individual elements will generally not equal the value returned from this function.

Examples

library(utils)

foo <- new.env()
foo$b <- 1:10
foo$d <- 1:10

objSize(foo) # all the elements in the environment
utils::object.size(foo) # different - only measuring the environment as an object

utils::object.size(prepInputs) # only the function, without its enclosing environment
objSize(prepInputs) # the function, plus its enclosing environment

os1 <- utils::object.size(as.environment("package:reproducible"))
(os1) # very small -- just the environment container

Description

This will pad floating point numbers, right or left. For integers, either class integer or functionally integer (e.g., 1.0), it will not pad right of the decimal. For more specific control or to get exact padding right and left of decimal, try the stringi package. It will also not do any rounding. See examples.

Usage

paddedFloatToChar(x, padL = ceiling(log10(x + 1)), padR = 3, pad = "0")

Arguments

Value

Character string representing the filename.

Author(s)

Eliot McIntire and Alex Chubaty

Examples

paddedFloatToChar(1.25)
paddedFloatToChar(1.25, padL = 3, padR = 5)
paddedFloatToChar(1.25, padL = 3, padR = 1) # no rounding, so keeps 2 right of decimal

Description

Allows a user to specify that their character string is indeed a filepath. Thus, methods that require only a filepath can be dispatched correctly.

Usage

asPath(obj, nParentDirs = 0)

## S3 method for class 'character'
asPath(obj, nParentDirs = 0)

## S3 method for class 'null'
asPath(obj, nParentDirs = 0)

Arguments

Details

It is often difficult or impossible to know algorithmically whether a character string corresponds to a valid filepath. In the case where it is en existing file, file.exists can work. But if it does not yet exist, e.g., for a save, it is difficult to know whether it is a valid path before attempting to save to the path.

This function can be used to remove any ambiguity about whether a character string is a path. It is primarily useful for achieving repeatability with Caching. Essentially, when Caching, arguments that are character strings should generally be digested verbatim, i.e., it must be an exact copy for the Cache mechanism to detect a candidate for recovery from the cache. Paths, are different. While they are character strings, there are many ways to write the same path. Examples of identical meaning, but different character strings are: path expanding of ~ vs. not, double back slash vs. single forward slash, relative path vs. absolute path. All of these should be assessed for their actual file or directory location, NOT their character string. By converting all character string that are actual file or directory paths with this function, then Cache will correctly assess the location, NOT the character string representation.

Value

A vector of class Path, which is similar to a character, but has an attribute indicating how deep the Path should be considered "digestible". In other words, most of the time, only some component of an absolute path is relevant for evaluating its purpose in a Cache situation. In general, this is usually equivalent to just the "relative" path

Examples

tmpf <- tempfile(fileext = ".csv")
file.exists(tmpf) ## FALSE
tmpfPath <- asPath(tmpf)
is(tmpf, "Path") ## FALSE
is(tmpfPath, "Path") ## TRUE

Description

The method for GIS objects (terra ⁠Spat*⁠ & sf classes) will crop, reproject, and mask, in that order. This is a wrapper for cropTo(), fixErrorsIn(), projectTo(), maskTo() and writeTo(), with a required amount of data manipulation between these calls so that the crs match.

Usage

postProcess(x, ...)

## S3 method for class 'list'
postProcess(x, ...)

## Default S3 method:
postProcess(x, ...)

Arguments

Value

A GIS file (e.g., RasterLayer, SpatRaster etc.) that has been appropriately cropped, reprojected, masked, depending on the inputs.

Post processing sequence

If the rasterToMatch or studyArea are passed, then the following sequence will occur:

1. Fix errors fixErrorsIn(). Currently only errors fixed are for SpatialPolygons using buffer(..., width = 0).

2. Crop using cropTo()

3. Project using projectTo()

4. Mask using maskTo()

5. Determine file name determineFilename()

6. Write that file name to disk, optionally writeTo()

NOTE: checksumming does not occur during the post-processing stage, as there are no file downloads. To achieve fast results, wrap prepInputs with Cache

Backwards compatibility with rasterToMatch and/or studyArea arguments

For backwards compatibility, postProcess will continue to allow passing rasterToMatch and/or studyArea arguments. Depending on which of these are passed, different things will happen to the targetFile located at filename1.

See Use cases section in postProcessTo() for post processing behaviour with the new from and to arguments.

If targetFile is a raster (⁠Raster*⁠, or SpatRaster) object:

*Can be overridden with useSAcrs.

**Will mask with NAs from rasterToMatch if maskWithRTM.

If targetFile is a vector (⁠Spatial*⁠, sf or SpatVector) object:

*Can be overridden with useSAcrs
