Thanks Elai, that did it! I never considered using any X11 options, as I'm on
Windows, and in the docs I read it sounded like X11 options only pertained to
the OSX/Linux/.. world. Thanks for your help, Doug

Doug,
dev.copy2pdf closes the connection after it's "done", so onefile is
meaningless. To look at each plot before copy to a single pdf, you
could open a pdf(...) but revert between it and your graphic device:
graphics.off()
plot(1:7, 1:7)
x11c<- dev.cur() # your current graphics device
pdf(file="test.pdf")
dev.set(which=x11c) # back from pdf
dev.copy() # copy
dev.set(which=x11c) # back to graphic
plot(1:5, 1:5,col=2,pch=2)
dev.copy()
dev.set(which=x11c)
# ... etc. however many more plots
# don't forget to close the pdf device at the end:
dev.off(which=x11c+1)
# Both plots are in 'test.pdf'
Depending on your application you might be able to simplify things
with dev.next/dev.prev, or wrap this sequence into a little helper
function to be used in a loop.
Enjoy,
Elai
