okay, good (I wasn't sure if it's the "correct" approach, that's why I
mentioned it here).

Martin Maechler suggested it at some point (we develop "copula") -- not
sure anymore why.

:-)

In principle, I agree. However, there are certain things that are simply
not possible with older versions of software packages (due to
org-contacts for example, I need emacs-snapshot).

Something I don't understand: I specified Sweave.sty (via the link) from
the 2009 basic TeXLive installation and it still did not work... (that's
why I wasn't sure I installed R/TeX correctly and that's why I gave the
information above).

(I didn't know this command, thanks).

I have the same output.

Again, same output.

Okay, so I try to achieve something similar by hand:

cd /usr/share/texmf/tex/latex
sudo ln -s /usr/share/R/share/texmf Sweave

Hmmm... still Sweave.sty not found (after texhash&  reboot) -- although
that's the tex tree of the 2009 TeXLive version.

For the 2011 TeXLive version, I tried the command I gave before -- still
without success. Unfortunately, the README of TeXLive 2011 does not tell
where the tex tree is it installs to. This would be helpful to determine
in which directory the symbolic link to /usr/share/R/share/texmk has to
be set.

Cheers,

Marius
