namespaces not available

Might it help to note that the version of MASS which shipped with 1.7.0 
didn't get the import of biplot from mva right?  I think this was what
happened with that version of VR.

This happens when one of the variables in your workspace contains a
reference to a name space, for eample as the environment of a
function.  The first warning is there because the workspace cannot be
loaded into older R versions.  THe second warning should probably be
removed.

(what is "biplot"??)

This I don't understand.  Loading a workspace with a reference to mva
or MASS (which imports biplot from mva) works fine for me, so there is
something more complicated going on.  Does a traceback() tell you
anything?  Otherwise, can you send me your .RData file and I will try
to track this down.
