To the best of my understanding and by following the documentation when I install R binary for Mac OS X both i386 and x86_64 are available. In fact I can easily choose among them by launching R Console by click on R or R64 "icons". But I'm not able to find the switch I must use to get the same thing when running R from the command line: I always get x86_64. I'm not able to solve this question by following R for Mac OS X FAQ or other sources of information available from CRAN.

For me, R32 and R64 do the job. They're simlinked to

R* -> /Library/Frameworks/R.framework/Resources/bin/R*

where * is 32 or 64. I don't remember setting those up, so they
probably happen automatically if you use the CRAN installer.
