R doesn't support 3D histograms?

Hi,

	I've been using R since a while now to make 2D histograms. I have 
some data (appended) that would like to use to make a 3-D plot with x being 
the first variable in the file, y the second and the height, or z the third
variable. How can I do it in R? I would like to have 3-D visualization of 
this plot. Preferably as a lego plot, that is, a set of stacks that grow 
with respect to the value of z, which have their delta x and delta y lengths 
equivalent to the spacings between the values of x and y. Other people also 
call it a 3-D histogram.

	Regards, Andre.

I don't know of such a function. You could try to "hack" you on function
around others, like cloud() in package lattice or scatterplot3d() in the
identically called package. Neither way will be easy or even very
promising.
As always, contributions are welcome, but if you are just going to
produce a few of these plots, I'd suggest to switch to another software
for that purpose.

There are some 3D contributed packages available.  Mine (djmrgl) has a
function called hist3d() that might do what you want.  It's available
for Windows only from my web page
<http://www.stats.uwo.ca/faculty/murdoch/software>  One of my projects
for the summer is to merge djmrgl with the other OpenGL project by
Daniel Adler; then (and possibly now) a cross-platform 3D histogram
will be available.
