[R] How to make eps out of a trellis graphic?

[Christian Hennig]

Hi list,

I produced a trellis graphic with qqnorm (R-package lattice, no changes in
graphical parameters were made).
1) The graphic uses some grey and some green colors and I would like to
have it black and white as usual.
2) I would like to produce an eps-file of it. Usually I do this with
something like

postscript("Rout.eps", horizontal=FALSE, onefile=FALSE,
           paper="special", height=8, width=8)
nr <- dev.cur()
dev.set(dev.prev())
dev.copy(which=nr)
dev.off(nr)
 
but this gives me an empty (plain white) eps-file this time.
So how to make an eps-figure out of my trellis plot?

Thanks,
Christian
