The drawback here, of course, is that the resolution of rgl isn't good enough
if you want to include the plot in a paper. For that purpose, I've recently
used panel.3dbars() from the "latticeExtra" package. I don't have a
self-contained example at hand, but the idea is to call the lattice function
cloud() and pass panel.3dbars() as an argument:
library("latticeExtra")
cloud( ... data and options ..., panel.3d.cloud = panel.3dbars)
See ?panel.3dbars for a complete example. I don't know how flexible these
plots are and whether you can exactly reproduce your example.
Best,
Stefan
