[R] 3d plots of mca() results?

[Andrew Perrin]

Greetings.

I'm about to embark on my first big (to me at least!) R project, which
will be to write a function to plot three-dimensional multiple
correspondence analysis (mca) plots in a manner similar to
scatterplot3d(). (plot.mca() plots only two dimensions, even though
mca() will calculate more.)  Before I do so, however, I would love to know
that I'm not reinventing the wheel or any other similarly common
implements. Has anyone done this before?

Many thanks.
