R help - Sep 2008 - annotating individual panels produced by xyplot

Hi all,

I'm new to R and lattice and panel functions.  I've produced a lattice
graph using xyplot.  Now I would like to add various, and *different*,
annotations to each individual panel.  I tried something like this,
using panel.text  ...

<code>
xyplot(dent ~ era | vegzone,
           groups=seedtype,
			panel=function(...) {
				panel.xyplot(...)
				panel.text(6.5,50,labels="my 1st annotation")
				panel.text(6.5,70,labels="my 2nd annotation")  } )
</code>

... but that didn't work, as both annotations appeared in all panels.
I want to control which panel each annotation appears in.  I feel
there must be a way to assign the contents of panel text to individual
panels, or to make a list of coordinates and annotations and have them
meted out over the various panels.  However, I've searched through the
R-help archives and just can't figure it out.

Any tips would be appreciated.  Thanks so much!
