Well, after running, there are less than 12 clusters with observations 
found by kmeans(). The error message suggests to specify initial cluster 
centers instead of randomly chosen ones, if you have got a rough guess 
where centers will be.

BTW: If you have got known "classes", don't you want to perform 
classification rather than clustering???
