R-patched is just the R sources.  After you have obtained a copy of
those sources via rsync, cd to the top-level source directory and run

./tools/rsync-recommended

This arrangement allows the authors of recommended packages to update
their packages on their own schedules, not necessarily on the schedule
for the R sources.
