well 2^32 gives you more like 4 GB, how much of that can be given to a 
process ....  my highest workspace reached 1.2 Gig. I will add another Gig 
... or 2  ....

I am assuming that R can address more than 2 Gig memory,  does anybody know 
if R has some other limitation that might be lower than the OS?
