[R] Lattice Version of grconvertX or variant on panel.text?

[Bryan Hanson]

Still playing with Lattice...

I want to use panel.text(x, y etc) but with x and y in plot coordinates
(0,1), not user coordinates.

I think if I had this problem with traditional graphics, I could use
grconvertX to make the change.  I did come across convertX {grid} but this
doesn't seem to be what I need.

Is there a function like grconvertX in Lattice, or is there a flag or some
other method of making panel.text use plot coordinates?

Thanks, Bryan
