[Rd] FC5 32-bit vs 64-bit

[Jeff Barrett]

Hello,
I am a biostats student and a newbie to R.  I have a question about  
32-bit vs. 64-bit.
I am running FC5 on a AMD 3800+ with 2GB Ram.  With 64-bit, I am  
running into some issues the stability of FC5.  A friend suggested I  
ditch the 64-bit version of FC5 for the 32-bit.  I do not currently  
have any pressing needs for the capabilities of the 64-bit OS. Before  
I reinstall the 32-bit FC5, I want to know the specific effects on R.

I see plenty of articles on 32-bit vs. 64-bit in general, but does  
anyone have any real comparisons of 32 vs. 64 bit using R?
