R help - Oct 2009 - 64-bit R on mac

Hi,

My Mac OS is Leopard. I downloaded
R-GUI-5496-2.9-leopard-Leopard64.dmg from http://r.research.att.com/.
I run R from the image disk, but it always "quit unexpectedly".

What could cause the problem? Is it because that I have a 32 bit R
installed already installed in the same machine.

Regards,
Peng

You probably need to install a 64bit version of R. The one distributed  
"normally" through CRAN isn't 32bit.

BTW, there is an R-sig-mac list that you should send mac-specific R  
questions to:

It is hard to say. If you were really trying to run R from the image,  
then that is just wrong. You want to use the disk image to install a  
copy of R.app onto your local drive. Drag the R.app icon into the  
Applications folder.  That is of course only the GUI "shell" and not  
the complete 64bit R interpreter. If that is all you did, you won't  
get what you expected, since the GUI won't find the needed 64bit  
interpreter code.

I would go back to the web page and read the instructions more  
carefully. I worry you may have skipped several other steps ( in  
addition to the instructions you overlooked on how to install the GUI  
app.)

Doubtful. Most people who have installed the 64 bit version have been  
in that situation, and it has not caused us problems.
