Help regarding kmeans output. need to save the clusters into different directories/folders.

Thu, Jan 24, 2013 2:14 PM

You find the element of clustering_tail that indicates which which point
is in which cluster (the help page for kmeans tells you). Then you use
that element to subset your input data (1.tsv). Then you save each subset
to a separate folder.

By "save to a folder" I would assume you mean write a tsv file, in which
case you use write.table().
