ballplot2

Ballplot2 plots spheres at the 3-d coordinates specified by x, y and z.

The function ballplot plots spheres at the 3dimensional coordinates specified by the vectors x,y and z. The vector I specifies the intensity of a fourth parameter at these coordinates.
The colour of the spheres is calculated using the colormap jet and the vector I. Type ballplot2 for a demonstration
