| unlink {base} | R Documentation |
unlink deletes the file(s) or directories specified by x.
unlink(x, recursive = FALSE, force = FALSE, expand = TRUE)
x |
a character vector with the names of the file(s) or directories to be deleted. |
recursive |
logical. Should directories be deleted recursively? |
force |
logical. Should permissions be changed (if possible) to allow the file or directory to be removed? |
expand |
logical. Should wildcards (see ‘Details’ below) and
tilde (see |
If recursive = FALSE directories are not deleted,
not even empty ones.
Wildcard expansion (normally ‘*’ and ‘?’ are allowed) 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.
