Sorry, my mistake: I meant scale_x_reverse() ...

You can set the size of the image device directly, e.g., png(....,
width = 400, height = 200) and then make your plots one per image,
closing the device with dev.off() when you're done. I think getting
multiple plots per page (without facetting) won't be super easy and
requires a few tricks with grid tools; someone might know better.
I know pdf() supports multiple pages if you plot multiple graphs and
don't close the device between, but I'm not sure that's doable with
the other ones.

I'm not sure what you are looking for here -- is there an image online
you can point me too?

As described above, you probably want to make multiple files by
looping over your data and selecting subsets. I know Bert pointed you
to xyplot in lattice graphics -- if you get that working, I believe it
has some natural support for multi-page graphics but I don't know the
package so well.
