An alternative to basename and dirname when there are sub-folders

Source: R/paths.R

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

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

Arguments

files

A character vector of files to check to see if they are the same as knownRelativeFiles, once the absolutePrefix is removed

absolutePrefix

A directory to "remove" from files to compare to knownRelativeFiles

knownRelativeFiles

A character vector of relative filenames, that could have sub-folder structure.

verbose

Numeric, -1 silent (where possible), 0 being very quiet, 1 showing more messaging, 2 being more messaging, etc. Default is 1. Above 3 will output much more information about the internals of Caching, which may help diagnose Caching challenges. Can set globally with an option, e.g., options('reproducible.verbose' = 0) to reduce to minimal
