At least in CRAN R it *is* 64-bit: $ Rscript -e 'sessionInfo()$platform' [1] "x86_64-apple-darwin9.8.0/x86_64 (64-bit)" in fact, it's universal: $ file `which Rscript` /usr/bin/Rscript: Mach-O universal binary with 2 architectures /usr/bin/Rscript (for architecture i386): Mach-O executable i386 /usr/bin/Rscript (for architecture x86_64): Mach-O 64-bit executable x86_64 $ file -h `which Rscript` /usr/bin/Rscript: symbolic link to /Library/Frameworks/R.framework/Resources/bin/Rscript so you get whichever is preferred by your system and you. Hence the problem seems with your setup, not R we provide.
