results from sammon()
Dear all,
I'm trying to get a two dimensional embedding of some data using different
meythods, among which princomp(), cmds(), sammon() and isoMDS(). I have a
problem with sammon() because the coordinates I get are all equal to NA.
What does it mean? Why the method fails in finding the coordinates? Can I do
anything to get some meaningful results?
Thank you very much
Domenico
