R help - Jun 2010 - How to draw multi group plot?

As the attachement,I wanna draw multi group plot.
But I can only use :
plot(x,y...) 
points(...)
 
It's a heavy work to use these command if there're too many groups to be
drawn because I have to use point(....) for many times.
 
I wanna know wheter there's command which can draw the multigroup plot
directly?
 
Thanks
 
My best.

It is hard to know exactly what you want without a description of your data or
what you want the final plot to look like.  But you can do the equivalent of
plot followed by multiple calls to points by using a loop, apply functions, the
lattice package or the ggplots2 package (I'm guessing the later 2 would be
the better place for you to start).
