Nothing against R, but the GNU equivalent (more matrix oriented
etc) is Octave, which is as close to the emulation of MATLAB as
you can get.

All parts should go together without forcing. You must remember
that the parts you are reassembling were disassembled by you.
Therefore, if you can't get them together again, there must be a
reason. By all means, do not use a hammer.

Asunto: [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.

P.
