[R] plotting intersecting planes

Hi all

In two days, I am giving a small, informal workshop in our
Department about using R.  Initially, it was just for statistician,
but surprisingly (to me anyhow) many mathematicians are also
coming who have a MATLAB background.  They are coming at the
Workshop from a teaching perspective.

They are considering using R to avoid licensing issues with
MATLAB.  One thing they were hoping me to show them was some
3D plotting.  I have used  persp  and  image  and all.  But what 
about, say, plottting intersecting planes?  I can't seem to find a 
way of plotting in 3D, and then adding another plot.
I guess I am after a 3D equivalent of  lines  or  points;
one plots the original plot and then adds to it.

Ideally, this would be a simple task; we wouldn't want to have
our students mucking about too much to plot two planes intersecting.

Thanks as always.
