| unlink {base} | R Documentation |
unlink deletes the file(s) or directories specified by x.
unlink(x, recursive = FALSE, force = FALSE)
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? |
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.
0 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.
