R help - Mar 2008 - Weighted histograms / distributions (retry)

Hi all,

I'd be greatful for any assistance with these two
problem I'm facing:

1. How can I combine weighted.hist() and multhist()
from the plotrix library so that I can display two
weighted histograms on the same chart ?  (if anyone
is familiar with a different library or function that
already does that, that would be great to know as
well )

2. How can I display weighted histograms or weighted
distributions in a lattice chart ? ( unfortunately,
lattice's histogram() is unweighted ).
   
Thanks very much!
Dave.
