Description

These functions are provided for compatibility with older versions of R only, and may be defunct as soon as of the next release.

Usage

filePathAsAbsolute(x)
filePathSansExt(x)
fileTest(op, x, y)
listFilesWithExts(dir, exts, all.files = FALSE, full.names = TRUE)
listFilesWithType(dir, type, all.files = FALSE, full.names = TRUE)

Arguments

x, y

character vectors giving file paths.

op

a character string specifying the test to be performed. Unary tests (only x is used) are "-f" (existence and not being a directory) and "-d" (existence and directory); binary tests are "-nt" (newer than, using the modification dates) and "-ot".

dir

a character string with the path name to a directory.

exts

a character vector of possible file extensions.

all.files

a logical. If FALSE (default), only visible files are considered; if TRUE, all files are used.

full.names

a logical indicating whether the full paths of the files found are returned (default), or just the file names.

type

a character string giving the “type” of the files to be listed, as characterized by their extensions. Currently, possible values are "code" (R code), "data" (data sets), "demo" (demos), "docs" (R documentation), and "vignette" (vignettes).
