Since I posted last night I've been exploring the possibilities of how the
two implementations could be different. The underlying algorithm appears to
be slightly but I think the main difference between the two is how the
initial seeds are chosen. In FASTCLUS I believe it's some sort of random

Hello all,
I've been comparing results from kmeans() in R to PROC FASTCLUS in SAS and
I'm getting drastically different results with a real life data set. Even
with a simulated data set starting with the same seeds with very well
seperated clusters the resulting cluster means are still different.
