Hi Gonzalo,

I haven't responded to your earlier post of this question because I don't
know the answer. In the last few days, I've managed to solve my problems
with the CLUSTER function by not using it! I've downloaded a program
written by Vincent Schmithorst called CCHIPS/IDL and there's a procedure
in this program package called ksegment.pro which I've modified and am
now using for my cluster analysis. And it works well!!
