We're planning to release 64 bit builds with R 2.11.0. They are
currently being built as part of the test process, though the builds are
still a little irregular. You can download from <CRAN
mirror>/bin/windows64/contrib for now, and soon from <CRAN
The 64 bit versions of R will require a 64 bit version of Windows to run
on. I think there may be 64 bit versions of XP, but they are uncommon
and I don't know if they support our builds; we're testing in 64 bit
Vista and Windows 7.
Revolution Computing also sells a build produced with a different
compiler. It has the advantage that the compiler is probably in better
shape than the one we are using and they'll provide support with it; the
disadvantage is that they'll charge for it, and they are probably not as
up to date as us with respect to released version number.
