[R] Deleted objects keep coming back

[Ken Termiso]

Ah! I think this is what happened -- whenever I restarted R, it would 
automatically load the previous workspace and its objects (call this 
workspace 1). Then, when I would attempt to load another workspace (call 
this workspace 2), it would retain the objects from workspace 1 in ADDITION 
to the objects loaded from workspace 2.

If I load up R, it will say previous workspace restored. If I then type 
 >rm(list=ls()) to delete all objects, and then load another workspace, it 
will only have the objects from the workspace I loaded...

Am I correct here?

Thanks, Andy.
