Hello,I have used Matthew's method to install 64 bit R on Leopard (http://www.matthewckeller.com/html/64_bit_r_on_mac.html
) and from the command line in the terminal program both 32 bit
(command "R") and 64 bit (command "R --arch=x86_64") R seem to
work. My question concerns the R GUI. The page http://r.research.att.com/building.html
indicates that "Leopard supports 64-bit throughout, including in
the R GUI". The GUI downloaded from http://r.research.att.com/
opens 32 bit R, but I have not been able to get the GUI to open 64
bit R. Please tell me what I am missing. Does the GUI need to be
recompiled, is there a configuration that needs to be set, or have I
misunderstood the statement "64-bit throughout, including in the R
GUI".R is installed on a Mac Pro with Quad-Core Intel Xeon
processors and Mac OS X 10.5.4 operating system. Thank you,Kurt Newman

First a warning - please don't follow all "Matthew's instructions"
unless you really know what you're doing. They are slightly misleading
and most of the them are not necessary (and some are outright
dangerous). If you think the instructions on http://
r.research.att.com/ are not sufficient, please say so!
As for the GUI, you have to compile 64-bit version of the GUI once you
have 64-bit R installed. You can do so as follow (paste in the
Terminal, you must have Xcode installed):
svn co https://svn.r-project.org/R-packages/trunk/Mac-GUI
# svn may ask you to accept ETH certificate here if run for the first
time
cd Mac-GUI
xcodebuild -configuration Deployment64
open build/Deployment64
The last command will open the directory containing the newly built
GUI in the Finder, so you can do whatever you please with it (replace
the 32-bit, rename, copy to Applications, ...)
As for installing Leopard R, the simplest way is to paste this in the
Terminal:
curl -s http://r.research.att.com/R-2.8-branch-leopard-
universal.tar.gz \
| sudo tar fvxz - -C /
You don't need extra library paths for 64-bit packages, but you want
to use type='source' in install.packages for 64-bit (as the site says).
Cheers,
Simon
