    If you compile R as a 64 bit application you should be able to address more
than 4GB of ram, but I'm not sure if R will support this. Also 32bit 
applications will run a bit faster since their pointers are smaller and thus
more information can be kept on cpu caches.  The difference isn't that big 
however (I think it's about 5% or so).
