In my situation under windows xp, after I setting the environment
variable R_LIBS, neither Rgui.exe nor Rterm.exe under cmd.exe doesn't
know the existence of R_LIBS.
After I enter the R interface, I find .libPaths() can add a new location
for installed packages:
> .libPaths("d:/progra~1/R/Rlibs")
> .libPaths()
[1] "d:/progra~1/R/Rlibs" "D:/PROGRA~1/R/R-27~1.2/library"
Then the install.packages will install the packages into the first
directory. But after I restart R, I have to set it again. I cannot find
some configuration file to set it permanently.

On a windows machine you get the same problem. Useless one uses tha same
trick as Rolf suggested: don't install the packages in the default
directory and set R_LIBS to that directory. Then all you need to do
after an upgrade is to set R_LIBS in the new version and run
update.package(checkBuilt = TRUE). Given Rolf's suggestion I suppose
this trick will work on a Mac too.

To call in the statistician after the experiment is done may be no more
than asking him to perform a post-mortem examination: he may be able to
say what the experiment died of.

I'm not sure --- I find Mac OS very confusing. But I have the
***impression*** that
(on my system) by default packages get installed into
~/Library/R/2.7/library
i.e. into a library inside the directory tree rooted in my login
directory.
I don't use this --- I've created my own library ~/Rlib and have
set up an environment variable to point to it.
(This works properly only if you start R from the command line;
for
reasons I don't understand if you start R by clicking on the
icon
then R doesn't know about the R_LIBS environment variable. But
since
all civilized people start R from the command line .....)
I have no idea why youse guys' systems would eschew using
~/Library/
<whatever>.
cheers,
