[R] panel.text and saving to pdf

[willem vervoort]

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().

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.

Best,
Uwe Ligges
