If you already know svn then google code is very easy to use.  Setting
yourself up on it is really just a few minutes of work in that case.  I have
used other similar sites but google code is by far the easiest one to
work with of the ones I have tried. By default everyone has read access
and only you have write access so you still control the project.  You can
browse through the R projects that are already in google code here:
