Thanks a lot for the quick help! How to project the scatter plot
with the
diagonal line to the three planes with scatterplot3d? I could not
find such
an example demonstrating that in the vignette.
I'm puzzled. If you have (x1, y1, z1) and (x2, y2, z2) as starting and
ending points, Deducing the three projected segments , i.e. the
starting and ending points of the projections on the xy, xz and yz
planes (z = 0, y=0, and x= 0 respectively) would seem to be trivial.
So maybe I just don't understand. What part is offering difficulty?
Please show your code so far.

scatterplot3d or something else?
Yes, scatterplot3d, rgl, and maybe also others.
For looking at it interactively I always prefer rgl, for statical
representations (e.g. printing) scatterplot3d can be used with all
known R
devices.
