Cool, Barry.
I set n=30, col="red" and stuck it into my daiquiri!

Greetings,
I would like to add 3D arrows (i.e. arrow-headed vectors linking X1Y1Z1 to X2,Y2,Z2) to a 3D plot; ideally the sort of plot that can be rotated interactively. Is this possible using plot3d, or another 3d plotter in R?
While it is easy to draw segments in plot3
