R help - Aug 2002 - Jpeg files dynamically but multiple figures (e.g xyplot (grid/lattice))...

Dear List,

Some days ago, it was posted in this list a question regarding "How to
generate graphics (jpeg) files dynamically". Although it was responded,
there is a particular case in which I do not find the rigth solution.

My question also goes in the same direction but for the particular case of
generating jpeg/bmp or png files when using xyplot (grid/lattice libraries) and
the output is displayed in more than one window and its you do no have the
control over the multiple figures except for allowing them to be displayed
(par(ask=T/F)).

I know that there are alternatives like the pdf and postcript commands or even
the obvious one to capture the different windows manually, but is any other way
to capture it dynamically ?.

Thanks in advance,

Carlos.

P.S: Attached are the details of the R version I have.

There is currently no simple way to make more than one plot with a jpeg()
device, nor with bitmap().

I'll look into adding a onefile=FALSE argument to jpeg similar to that
used for postscript().  Not likely for 1.6.0, though.
