Hi Tony,

Concerning (3) Sweave. I found a fairly easy way to rerun selected 
commands. I split my whole document into two parts, the main part with 
\begin{document} .... \end{document} and the minor part which contains 
all the commands I do not want to rerun. The trick is to comment/ 
uncomment a line  \SweaveInput{minor}

%%% major.Rnw:
\documentclass[10pt,a4paper,leqno]{scrartcl}
.....
\begin{document}

%%  comment/uncomment:  \SweaveInput{minor.Rnw}

%% modify & rerun just selected commands:

\end{document}

%%% end major.Rnw

---------------------

%%% minor.Rnw

%% all the text and commands which need not be rerun.

%%% end minor.Rnw

--------------------

This procedure will, however, only produce a .tex without the parts not 
to be rerun.

How to produce the full document without rerunning the whole .Rnw, would 
require some work on the part of the Sweave authors.

Christian
