silly SVN question

 I followed the suggestions at
http://developer.r-project.org/SVNtips.html to check out an anonymous

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)?

https://svn.r-project.org/R-packages/trunk

but

- not all of the recommended packages are there.
- Matrix and survival have migrated to R-forge
- in some cases what is on the svn archive has lagged the release
   version.

It is most useful for the packages maintained by R-core collectively.
