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

Thanks for the attention paid to my rpoblem. Please find enclosed
the matrix with my dissimilarities. This is the only case in
which sammon(), from the MASS package, gives me this kind of problems.
