hadley,
thanks for the example, that put it much better into perspective. I'm
gonna make some coffee and read through this page and see how deep it
goes. I might even be able to use this for some other things we're
doing.
Thanks!

I really would encourage you to look at ggplot2 before trying to
create something of your own. Your example would convert to the
following ggplot2 code:
df <- data.frame(x = 0:3, y = 3:0)
plot <- ggplot() + xlim(-3, 3) + ylim(-3, 3) + opts(main = "Hello World")
plot + geom_line(aes(x=x, y=y), df
I believe I've found a way to wrap and use dev.cur()[[1]] to have the
desired effect. I'm just leaving my terminal now, but I'll post these
results on monday so everyone can see how it turned out.
If you have any ideas or qualms with this method, please let me
know.
Thanks Duncan!

I'm not so sure the original way I stated my issue was clear enough,
so I'll attempt to elaborate a little bit.
I'd like to make a function that is passed the name of a plot object,
and a lines/point specification, and graphs them all on the same plot.
I don't want to redraw the plot each time, a

I don't think so. You can see if a graphics device is open by looking
at dev.cur(), but I don't think there's a test for plot.new(). I'd just
wrap the call in try() if you're no
