Now you have changed plotting functions from plot and barplot over to
barchart (a Lattice function) and were not aware of FAQ 7.22:

Could you please paste the exact code you are using? (the one with
the pdf and
dev.off, outside the loop )

I suspect that using "dev.copy2eps" Is not going to help you here.
Please try again using:
pdf(...) # Check: ?pdf
for(i in something)
{
plot(things)
}
dev.off()
But give pdf() the file path.
Make sure you can make it work with simple plots. then check it
on
your
situation, and let us know if it works :)
(I had it work with very heavy plots - so I trust it will work for
you)
(p.s: please keep cc'ing the r-help list so others will know the
stage of your
problem, in case others would like to add more help :) )

The problem is that the filename changes with each iteration of the
loop, so I need to
save the graph inside the loop.
I tried this:
for(...)
{
...
pdf(...)
barplot(...)
}
but I just got a load of empty graphs.
Because you failed to follow Ted directions to use dev.off()
pdf() just opens the file for writing, dev.off() executes the
writing
and closes properly.

I just tried with dev.off() but still the same problem.
I tried with pdf() and dev.off() inside the loop, and with them
outside
(pdf before the loop,
and dev.off after). Same results each time: an empty pdf file.
I am using R version 2.11.1 if this makes any difference.
