[R] Mixing portrait/landscape in a postscript file

[Yves Brostaux]

Dear list,

I'm stuck with a little graphical problem. I'm generating several 
lattice plots which are printed in a single postcript device opened by

 > trellis.device(postscript, theme=canonical.theme("postscript", 
color=F), file="an_phase2_graph.ps", paper="a4", pointsize = 10, 
onefile=TRUE, horizontal=TRUE)

Everything works fine,but some of these plots shoud be printed in a 
portrait orientation to look better. I tried to include [...] 
par.settings = list(horizontal=FALSE) [...] in the lattice plots 
arguments, but with no success. Is there a way to mix different page 
orientation in a single postscript device that I missed ?
