An example on how to draw segments for residuals on a regression plane 
with scatterplot3d is shown in Section 4.2.2 (pp. 20-22) of

Ligges, U. and Mächler, M. (2002): Scatterplot3d - an R Package for 
Visualizing Multivariate Data. Technical Report 22/2002. SFB 475, 
Department of Statistics, University of Dortmund, Germany.
