R running on my MacPro under OS X 10.6.8 no longer installs packages.  I
would greatly appreciate help in sorting this out.

Typically I get the messages like:

Warning: unable to access index for repository
http://software.rc.fas.harvard.edu/mirrors/R/bin/macosx/leopard/contrib/2.13
Warning message:
In getDependencies(pkgs, dependencies, available, lib) :
   package ‘party’ is not available (for R version 2.13.1)

Version 2.13.1 is very old; you might find that package binaries are not maintained for such an old version, and current versions of the packages might not work in it. I would update to R 3.0.2.

The repository URL mentioned in the first warning indicates leopard, not
snow leopard, the name for OS X 10.6.8.  Is this an issue?  If so, what to
do?

The second message seems to indicate that I might need a different version
of R.  If so, which?  How to preserve the existing version while checking
out the new version?

And version seems to indicate darwin9.8.0.  Any idea why?

Otherwise R is currently functioning fine.  I really don't want to screw
that up.  If there is a fix without installing a new version, I would like
to try that first.

I've never updated to a newer version, and it's been a while since I
installed on a mac, so step-by-step instructions are needed.

Thanks,

Carlisle
