[R] several plots on several pages

[Greg Snow]

Oops, I read further down in your original post and see that you already
knew about par(mfg=c(2,1)).  To get it to advance to page 2 for the 4th
plot try calling plot.new() which should move you to the next page, then
doing par(mfg=c(1,1)) should cause the next graph to be at the top.

Hope this helps,
