R help - Oct 2009 - Print several xyplots to the same page in a pdf file

Hello everybody,

I'm using the lattice package and the xyplot to make several graphs like
below. However, I can just print the three grouped plots onto one page as
I'm putting them into a pdf-file, which gives me a huge amount of pages...
Is it possible to put them all, or at least more than one on the same page, for
instance put three groups beside each other like columns?

...
xyplot(Pro ~ Glc | Categories_BBCH_ID, data=fieldTrial0809, pch="°",
layout=c(1, 3), aspect=1, index.cond=list(3:1))
xyplot(Pro ~ Raf | Categories_BBCH_ID, data=fieldTrial0809, pch="°",
layout=c(1, 3), aspect=1, index.cond=list(3:1))
xyplot(Pro ~ Suc | Categories_BBCH_ID, data=fieldTrial0809, pch="°",
layout=c(1, 3), aspect=1, index.cond=list(3:1))
xyplot(Fum ~ Aa | Categories_BBCH_ID, data=fieldTrial0809, pch="°",
layout=c(1, 3), aspect=1, index.cond=list(3:1))
xyplot(Fum ~ Pro | Categories_BBCH_ID, data=fieldTrial0809, pch="°",
layout=c(1, 3), aspect=1, index.cond=list(3:1))
etc...

All the best,

Joel

Check the documentation and examples for print.trellis; I prefer the
"split"
version, but other are possible. And do not forget that it is best to do an
explicit print.

p1 = xyplot(....)
p2 = xyplot()

print(p1,split=c(1,1,2,1))
print(p2,split=c(2,1,2,1))

I'm not entirely sure what you want, but what about some variant of

xyplot(Pro ~ Glc + Raf + Suc | Categories_BBCH_ID,
data=fieldTrial0809, outer = TRUE,
       pch="?", layout=c(3, 3), aspect=1, as.table = TRUE)
