[R] Unix-like permissions to allow a user to update recommended packages

I installed R from the tar.gz file (as root) in a directory under
/usr/local.  The recommended packages are installed in a library in
that directory whereas additional packages I install in a directory
under the /home directory as a user.

Updating the additional packages is very easy with update.packages()
as a non-root user, but the recommended packages cannot be done so
readily because of file permissions.

My question is how do I set the permissions or ownerships in the
/usr/local/R-2.5.0 directory so that everything necessary can be
writable by a user?  Should I make a group for R users (total of one
member) or is it simpler than that?
