unlink {base}R Documentation

Delete Files and Directories

Description

unlink deletes the file(s) or directories specified by x.

Usage

unlink(x, recursive = FALSE)

Arguments

x a character vector with the names of the file(s) or directories to be deleted. Wildcards (normally ‘*’ and ‘?’) are allowed.
recursive logical. Should directories be deleted recursively?

Details

If recursive = FALSE directories are not deleted, not even empty ones.

file.remove can only remove files, but gives more detailed error information.

Value

The return value of the corresponding system command, rm -f, normally 0 for success, 1 for failure. Not deleting a non-existent file is not a failure.

Note

Prior to R version 1.2.0 the default on Unix was recursive = TRUE, and on Windows empty directories could be deleted.
