In 'R for Windows FAQ' for R version 2.11.0 Patched (2010-05-11 r51982) you can read:
[2.29] Can both 32- and 64-bit R be installed on the same machine? Obviously, only relevant if the machine is running a 64-bit version of Windows. Yes, with a little care. For R 2.11.x they should be installed into different directories: the installer will suggest that the 64-bit build is installed into, say, R-2.11.0-x64 and Administrator installs will default to different paths (e.g. C:\Program Files (x86)\R for 32-bit, C:\Program Files\R for 64-bit). The Start Menu, desktop and quick launch icons will be named differently, and the versions can be uninstalled independently. Aren't those paths vice versa? 32-bit: C:\Program Files\R 64-bit: C:\Program Files (x86)\R (I've noticed that this paragraph is not in R v2.12.0 dev). /Henrik ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
