[R] Deleted objects keep coming back

[Ken Termiso]

Having a very strange and frustrating problem with v2.0.1 under Mac OSX 
10.3. I have several closely related workspaces in the same directory that I 
need to keep separate from one another (there are a few objects common to 
all workspaces, and then there are other objects that store the results of 
different analyses on the common objects, which is why I need separate 
workspaces).

When I attempted to delete objects with rm() and then re-save the workspace, 
after quitting and restarting R, reloading the workspace, the objects were 
still present in the workspace (even though I'd deleted them).

So I deleted the objects again with rm() and also called gc(), and saved the 
workspace with a new name. I then quit R and reloaded the workspaces, and 
that seemed to work. The deleted objects stayed deleted.

But then an hour later, I came back and reloaded these workspaces, and the 
old objects which I'd deleted had come back again. This is really annoying 
and I feel like I'm losing my mind! I'm concerned that R is not accessing 
the directory properly, and may be reading one workspace file in place of 
another. This would completely jeopardize my work.

Please help!
Thanks in advance,
Ken
