You most likely don't have permission to write to that directory. Run
R as a user with enough permissions (usually you have to be an
administrator or similar to do that), or ask an administrator to
update the packages for you. If all else fails, you can create your
own R library (somewhere on your disk where you have write access) and
install updated packages in it.
