Re: [R] 64-bit R on Intel Xeon EM64T running fine
This is good news. As far as I know R has built for quite some time now on a number of 64 bit platforms (Linux on AMD Opteron/Athlon64, Solaris/Sparc) but I can't recall seeing a build on Intel with the 64 bit extensions.

I've been running a 64 bit-compiled R on an SGI octane 2 for over a year now without a problem.

RE: [R] 64-bit R on Intel Xeon EM64T running fine
This article might be of interest to some: http://www.linux-mag.com/2004-07/athlon_01.html Regarding 64-bit build of R, I can confirm Irix, Alpha and AIX, although some w/o readline/jpeg/png/X support, partially because of difficulties linking against 64-bit version of those libraries.
