[R] Where is global environment?

[Mike Prager]

I am using R 1.9.1 under Windows XP Professional.

Is there any R function that returns the filesystem path from which the 
global environment (workspace) was loaded (and to which it will, by 
default, be saved)?  This seems identical with the current directory, so in 
any given session it is not too difficult to find out by other means.  But 
for several reasons I would like to find this out from within R.

Thanks.
