Sweave and executive summaries

   I'm learning to use R/Sweave/LaTeK to write my stat reports.  Is there a way

   analysis  code  embedded?  

Thanks to Ulrich Dietz from the German latex forum, I have an excellent
solution that can write summaries (for the top) and appendixes. It
is pure latex, but it main power comes when using it with rnw/Sweave.

The idea is to have sections that are written out to a file similarly
to bibtex, and are collected later. You can download a minimal self-
running example from

(Make sure that you do not ask any more latex related questions here, 
you are running the risk of receiving a flame mail by higher authorities)
