R on Large Data Sets (again)

- Is a Unix-like platform a better option than win-64? Again, would
this solve my memory limitation problems?

Possibly, but Win64 should provide plenty of memory (I believe Windows 7
Ultimate can use up to 192 GB of memory). You just have to find the
system that can take that much... With Unix/Linux you can probably cut
back some overhead, and the memory management is most likely better, but
unless you need to go over 192GB of memory, you don't necessarily have
to move to a different platform.

Windows 64-bit can certainly handle large memory spaces, but unless
something has changed recently it my understanding Revolution
Computing's 64-bit is the only 64-bit version of R available for
Windows (due to the unavailability of adequate open source compilers
for 64-bit Windows).  So 64-bit R will need to be Revolution's
solution or a non-Windows platform.
