Can I specify centroids for kmeans to use for clustering?

I'm trying to insist that the centroids of my clusters stay consistent from one clustering to another. I'm running kmeans for each year in my data set, and I want the cluster centroids to be the same as the ones that were produced when I clustered the climatology.

Thanks, Nick

Peter answered your question in CSSM. Can you say why you don't like his answer?

I didn't realize Peter had responded. His response is great. Thanks.
