My first idea was to add
cex = iris$PetalLength,
which failed, taking the first value of cex only. In panel.3dscatter
I found the line
cex <- rep(cex, length.out = n)
Which looks like cex is not vectored. So my approach would be to make
a copy of panel.3dscatter and do the correct cex replacement there.
I might be wrong, however, Deepayan has the last say.
