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 Anders Sj??gren PhD Student Mathematical Statistics Chalmers University of Technology G??teborg, Sweden
64-bit R on OS X/G5?
2 messages · Anders Sjögren, Brian Ripley
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.
