I suspect Luigi that if you wrap the call to xyplot in print( )
matters might be improved.

Dear all,
with the most useful help of Duncan I updated a script to plot high
density data in the form of 384 squares containing tiny plots. The
function works and it is possible to create a pdf version of the
output. but when i try to make a function out of this script, the
resulting pdf file is empty.
Any tips?
Thank you and best regards,
Luigi
