silly SVN question

I followed the suggestions at
http://developer.r-project.org/SVNtips.html to check out an anonymous
copy of the development branch of R, but so far I have been unable to
figure out an analogous way to track the development branch of the
recommended packages. (I'm assuming they actually live somewhere on the
same SVN server, which might not be true ...) Any ideas (including
pointing out the obvious, or the obvious-in-hindsight)?

  thanks
