Hm. Sometimes workspace cannot be loaded when some packages which vere used for
creationd objects in workspaces are missing, but in that case the error message
is different.

So you either can delete .RData but it obviously **delete** all objects or you
need to find which package is missing from your R3.0.0 installation.

If you want to keep only some objects from your workspace return back to 2.15.3
and save them explicitely

see
?save

Tamas sent me a copy of the bad file, and I've got a workaround:

The problem is an object called .SavedPlots.  It was produced by the 
Windows graphics device when it was recording the history.  It can't be 
loaded into R 3.0.0, because some of the internal organization of things 
has changed.

The workaround is to restart 2.15.3, load the workspace, then

rm(.SavedPlots)

and save the workspace.  After that things should be fine.

I'll try to get something in place in R-patched so that this doesn't 
cause the whole .RData load to fail.
