Deletes the 00LOCK directory accidentally left behind by a fail in
install.packages.
Usage
p_unlock(lib.loc = p_path())
Arguments
lib.loc
Path to library location.
Value
Attempts to delete a 00LOCK(s) if it exists. Returns logical
TRUE if a 00LOCK existed and FALSE if not.
Details
Sometimes install.packages can "fail so badly
that the lock directory is not removed: this inhibits any further installs to
the library directory (or for --pkglock, of the package) until the lock
directory is removed manually." p_unlock deletes the directory
00LOCK that is left behind.
