[R] CRAN: 64 bit OS X Leopard build

[Prof Brian Ripley]

This thread really belongs on R-sig-mac!  I am answering here since if 
people are going to ask here, some general information would be 
appropriate, but PLEASE follow up only on R-sig-mac.

The CRAN Mac OS X page is a little confusing.  The main CRAN 
distribution of R is for Mac OS X 10.4 and later and has i386 and ppc 
architectures.  That is what is in R-2.9.0.dmg, and the appropriate 
binary packages are in the subdirectory 'universal'.

Then there are builds on http://r.research.att.com/.  These include a 
'leopard build' at http://r.research.att.com/R-2.9.0.pkg, which has 
i386, x86_64, ppc and ppc64 architectures.  The confusion is that the 
'leopard' directory on CRAN has binary packages for *that* build. 
(Note that the r-release and r-devel links are outdated in that 
directory.)

Note that there are no distributed '64 bit builds': each build has a 
collection of architectures.

However, as far as I recall (I normally use my own builds, including 
for x86_64), you do not need to know where the binary packages are, 
since the R.app 'Package Installer' menu item and install.packages() 
have the correct repositories pre-set.  If that is not working, you 
need to set options(pkgType="mac.binary.leopard") (see ?options and 
?install.packages).
