[R] 3D version of triax.plot (package plotrix)

[Gabriele Esposito]

Hi Jim,

thanks! With just the rgl package I cannot do that. For the moment, I
merged two values into one and use triax.plot in the package plotrix,
but that's not fully satisfactory. If you find something, let me know,
thank you a lot!

Gabriele
