unlink {base}
Delete Files and Directories
Description
unlink deletes the file(s) or directories specified by x.
Usage
unlink(x, recursive = FALSE, force = 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?
- force
- logical. Should permissions be changed (if possible) to allow the file or directory to be removed?
Details
Tilde-expansion (see path.expand) is done on x.
If recursive = FALSE directories are not deleted, not even empty ones.
Wildcard expansion is done by the internal code of Sys.glob. Wildcards never match a leading ‘.’ in the filename, and files ‘.’ and ‘..’ will never be considered for deletion.
Values
for success, 1 for failure, invisibly. Not deleting a non-existent file is not a failure, nor is being unable to delete a directory if recursive = FALSE. However, missing values in x are regarded as failures.
