I used synaptic to tell me which Debian packages came from r-cran, and I tried deleting them in synaptic. I did not delete those that also wanted to delete r-base, but I forgot to pay attention to the list of packages that are available in the Debian cran3 archive. Then I updated the sources list and did a safe-upgrade. I think that process may have left most or all of the packages in place that the safe-upgrade could fix, but it won't seem to matter. >> - http://www.r-bloggers.com/upgrading-r-and-packages/ suggests a script >> that updates installed packages.

It seems to have worked well. I wonder if you could also say "Delete any packages using synaptic or aptitude /except/ for those which want to delete r-base, as well"?
