You have not shared with us the "at a minimum" information requested  
in the Posting Guide (although your silly corporate confidential  
trailer was appended), so take a moment now and read the Posting  
Guide, please.

The saved workspace can be deleted. It is a file named .Rdata and in  
some OSes is "indivisible". Consult your OS documentation (such as it  
may be) regarding deleting  "invisible" or "dot" or system files.

You can also start R without any workspace if starting R from a  
command line and I believe that it is done with the --vanilla setting.  
Yes, that seems to behave as I expected. (I generally use the Mac GUI.)

 From a Terminal session:
david-winsemiuss-mac-pro:~ davidwinsemius$ R --vanilla

R version 2.11.1 Patched (2010-06-14 r52281)
---snipped login information----
Type 'q()' to quit R.

 > ls()
character(0)

In fact it seems to have also skipped loading my utility functions  
from .Rprofile as well as skipping the workspace .Rdata file.
