Ducan, As always, you are very giving of your time to help R users. Thank you!
scatter3d is from the car package. As I understand snapshot3d, it takes a screen shot and saves the resultant file. This implies that the resultant file will be 72 DPI. I need to get a higher resolution image, at least 300 DPI. Do you have any suggestions? Thanks as always.

To save an rgl image, you use the rgl::snapshot3d() function. It only has support for saving to PNG format. If you are writing your manuscript in R Markdown or knitr Rnw, there are ways to have the file included automatically. There have been methods to use with Sweave as well, but those aren't being maintained: people should use knitr instead.
