R help - Jun 2004 - 64-bit R on OS X/G5?

Hi!

Does anyone know if there is a working 64-bit version of R for MacOs X 
on G5? If so, is there a memory limit anyway or could I theroetically 
use almost 8 GB in one session?

Best regards

R works on 64-bit platforms and has for quite a while, currently I know of 
people using machines with 16Gb RAM on 64-bit platforms (Alpha, Sparc, 
AMD64).

Do you have a full 64-bit compiler and runtime for MacOS X?  If so `all'
you need to do is to run compile under it.  One quote I picked up was

	macos X has 64 bit support with gcc 3.3 and a g5

which if correct suggests this is possible.

There is of course a memory limit but it far exceeds 8GB.  There is a 
limit on the length of vectors still (2^31 - 1) and a few other similar 
limits.

I guess you could add AIX to that list, although not without pain (no
readline because the readline installed on that system is 32-bit).  If I'm
not mistaken, 64-bit R on Irix has also been done.

Best,
Andy
