If it is not the device then it's probably just the usage of an
unexpected unit somewhere - as reported in another reply by another
helper to your original question on R-help.

Hi Uwe,
I should send these messages from my member e-mail number
Thanks for that.
As you can see from the last bit of my code, I tried that, but it gave
the same results. I had a look at pdf.options() but didn't see
anything there either to make the text stay on the same spot. It seems
to also happen if you use png().

Subject: Re: [R] panel.text and saving to pdf
To get reproducible results, I highly recommend to print the lattice
graphics directly into the desired device, i.e. start the pdf >(or jpeg
or whatever) device before printing.

Dear all,
I am not sure what I am doing wrong, but I have some unexplained behaviour when
saving a lattice graph including text to a pdf file. The text seems to move
around. It must have something to do with the way coordinates are set in
devices other than jpg.
Any suggestions would be helpful
Willem
Here is some example code
setwd("c:/willem/research/misc")
today <- format(Sys.Date(),"%Y%m%d")
x <- runif(500)
y <- rnorm(500)
foo <- data.frame(x = x, y = y, z = rep(c("a","b"),250))
require(lattice)
xyplot(x~y|z,data=foo)
panel.text(370,470,"silly graph",cex=1.2,font=2)
savePlot(paste(today, "jpgplot",sep="_"),type="jpg") # this plots fine and text
is as on the screen
savePlot(paste(today, "pdfplot",sep="_"),type="pdf") # text has moved
pdf(paste(today,"pdfplot2.pdf",sep="_")) # no difference using pdf
xyplot(x~y|z,data=foo)
panel.text(370,470,"silly graph",cex=1.2,font=2)
dev.off()
# There is also no difference
