Hi,
Please tell me of an R graphical routine that will create a 3d plot
something like cloud or scatterplot3d but that allows individual
labeling of each point in the plot. I've done it with SPSS. I'm sure that
there is an R routine, but I can't find it.

Indeed in the case of a lazy-loaded package it looks a bit tricky, but
it should still be possible, as I guess one can access the source code
