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.
What does "interactive" mean here? Do you want to turnit around or do
you want brushing like interactivity?
For the former, I highly suggest to look at the rgl package

Dear Jeff,
I'm tempted to say that a scatterplot without points is an oxymoron, but
that wouldn't be very helpful.
Actually, the scatter3d() function used by the Rcmdr is in the car
package. The Rcmdr 3D scatterplot dialog doesn't provide for suppressing
the points, but if you add radius=rep(0, n) to the command that's
generated, where you'd replace n with the number of cases in the dataset,
that would do the trick by plotting spheres of 0 radius. For example, try
scatter3d(prestige ~ income + education, data=Duncan,
radius=rep(0, 45), residuals=FALSE)
either in the Rcmdr or at the R command prompt.
For more information see ?scatter3d or press the Help button in the Rcmdr
3D scatterplot dialog and follow the link to scatter3d.
I hope this helps,
John

Subject: [R] scatter3d
I am using scatter3d in R Commander to plot a group of regression
surfaces.
However, I only want to display the surfaces. How do I remove the points?
