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).
