? --> Algorithm::KMeans
With aforementioned module you can even choose the range of permitted clusters
# For very large data files, setting K to 0 will result in searching
+ through too
# many values for K. For such cases, you can range limit the values
+ of K to search
# through by
my $clusterer = Algorithm::KMeans->new( datafile => $datafile,
mask => "N111",
Kmin => 3,
Kmax => 10,
cluster_seeding => 'random',
+ # or 'smart'
terminal_output => 1,
write_clusters_to_files => 1
