well both actually. I would like to plot may (scatterplots or functions) in
one plot using color to separate the different species or fits, and I would
like to plot lots of little histograms over time in lots of little plots on
the page.

I've been able to plot lots of histograms in a page, although I need to
figure out how to use expf as a weight. basically I need to plot lots of
little bar charts, which I can do using par( mfcol=c(y,x)).

I've also had some trouble using the lattice package in a R script. when I
type the command xyplot( ht ~ dbh | species ) i get the plots i'm looking
for, when I try to produce the plots (to the screen) I get nothing. I need
to try to produce an eps file though.

thanks,
jeff.
