> x11(width=3.5,height=4,colortype="gray")
Then plotted (with matplot) a nice looking no-color graph on the screen, then I did this:
> dev.copy2eps(file="test.eps",height=4,width=3.5)
I was surprised that the output in the eps file included the colored lines from the plot, even though the screen device was set to "gray" and on screen I did not see colors.
I put some of the eps files up here, so you can see what I mean:

And if you don't have an eps viewer handy, I made png versions, since all browsers seem to show them.

The docs indicate that the x11 device is being copied, but I rather think that a plot object that exists "behind" the x11 device is being saved.?
I have since learned that I can put col=c("black") into the matplot command to make sure no colors are used, and that works the way I expect. But I was curious about this behavior in dev.copy2eps.
