Hello, I am using Mac OS on R. When I start R thru the application menu I have the option of running both the 32 bit version as well as the 64 bit version. When I type in R in terminal I believe it starts up the 64 bit version. How can I start the 32 bit version instead??

Try this in an R session:
if(.Machine$sizeof.pointer == 4){print("32 bit")} else
{print("64
bit")}
# for me it's .... [1] "64 bit"

What's the "application menu"? How did you install R?

Assuming you are looking at a Finder window for the /Applications/
directory ... What do you see?

What did you type? Just "R"? Pretty sure that gets you a 32 bit
version.

I'm betting you are already using a 32 bit version. All this Q&A would
be unnecessary if you included the results of sessionInfo()

A good place to set this is by adding the following line export R_ARCH=/i386 to ~/.profile Hope this helps! -Charlie -- View this message in context: http://n4.nabble.com/Running-32-bit-R-in-terminal-on-Mac-OS-tp978562p978928.html Sent from the R help mailing list archive at Nabble.com.
