If I go to: http://r-forge.r-project.org/scm/?group_id=18 and click on [Browse Subversion Repository] in the box to the right it takes me to a page that says this: Traceback (most recent call last): File "/usr/lib/gforge/bin//viewcvs.cgi", line 27, in import sapi ImportError: No module named sapi whereas I was expecting to get to the svn repository.
