Thank you all for the replies. However, I figured it now out, there is
nothing broken. The reason I got confused is only because there are
symbolic links used extensively and some tests failed in my script as a
consequence (see below).
My installation is fine and looks in fact like this:
afischli$ cd /Library/Frameworks/R.framework
afischli$ ls -l
total 40
lrwxr-xr-x 1 root admin 24 Jan 13 15:24 Headers ->
Versions/Current/Headers
lrwxr-xr-x 1 root admin 30 Jan 13 15:24 Libraries ->
Versions/Current/Resources/lib
lrwxr-xr-x 1 root admin 31 Jan 13 15:24 PrivateHeaders ->
Versions/Current/PrivateHeaders
lrwxr-xr-x 1 root admin 18 Jan 13 15:24 R -> Versions/Current/R
lrwxr-xr-x 1 root admin 26 Jan 13 15:24 Resources ->
Versions/Current/Resources
drwxrwxr-x 7 root admin 238 Feb 1 20:17 Versions
afischli$ cd Versions
afischli$ ls -l
total 8
drwxrwxr-x 6 root admin 204 May 24 2007 2.5
drwxrwxr-x 6 root admin 204 Nov 30 2007 2.6
drwxrwxr-x 6 root admin 204 Jan 13 15:24 2.8
lrwxr-xr-x 1 root admin 3 Jan 13 15:24 Current -> 2.8
This means there is nothing broken. The consequence is that R commands
such as:
> R.home()
[1] "/Library/Frameworks/R.framework/Resources"
> setwd(R.home())
> getwd()
[1] "/Library/Frameworks/R.framework/Versions/2.8/Resources"
give differing answers, which means that a test such as
setwd(R.home())
if (getwd() == R.home()) {
always fails, although the setwd command was actually successful. Guess
this all explains the problem and sorry for the bandwidth waste ;-)

It is present on my system (R reinstalled yesterday), so it looks like
you broke yours.
More precisely, there is a link at
/Library/Frameworks/R.framework/Resources to the correct place.
How did you think R could possibly work with this broken? R.home() is
used all over the place in R's own scripts.

R.home() returns "/Library/Frameworks/R.framework/Resources" although
there is
no such directory present. Inspecting the actual directory structure
of the R
installation indicates that the correct value R.home() should contain
is:
'/Library/Frameworks/R.framework/Versions/2.8/Resources'
Detected by af, ETH Zurich / 1.Feb.2009 using R 2.8.1 under Mac OS X
