Hi Thomas,
thanks a lot for your help!! Using the JSS and the org manual I solved all my problem (....at least for now!! :))

Hi Riccardo,

Thanks for the URL.  Org mode has evolved since this article was
written.  It should probably be revised or taken off Worg.  I've copied
Eric Schulte, who is better able than me to determine the correct course
of action here.

In the meantime, an up-to-date description of how Org mode can be used
to write literate programs has appeared in the Journal of Statistical
Software.  You can find it here: http://www.jstatsoft.org/v46/i03

Perhaps you could use the examples in the JSS article to get started?
If these don't work for you, or if they raise questions that are difficult
to answer, please do come back to the list with your queries.

All the best,
Tom
