[R] scatter3d

Thank you for the suggestion. Yes, it does seem to be a bit
counter-intuitive, but that is the output I am being asked to produce. I
have only been using R for a few weeks, so there is probably a better way
to do it.

Anyway, your suggestion did work, but only up to 337 data points. I am
dealing with ~100,000 data points so this doesn't really work for me. Is
there another method you would suggest? My goal is to plot multiple
regression planes (without points) in an interactive 3d plot.

Thank you,
Jeff
