And even more for the heck of it... this kind of thing is also
device-dependent.
(this is *not* a controlled test; some variation could be due to other
processes running on the machine)

That is a function I did not know about, thanks Hadley!
I still don't see the speed increase that you do with the base plot
package, but I'm sticking with ggplot anyway!

You need: system.time(print(qplot(x,y,pch=I('.'

Hi all,
I'm working with a bunch of large graphs, and stumbled across
something useful. Probably many of you know this, but I didn't and so
others might benefit.
Using pch="." speeds up plotting considerably over using symbols.
