[R] clustering, don't understand this error

[Christian Hennig]

Hi there,

I'm travelling right now so I can't really check this but it seems that 
the problem is that cluster.stats needs a partition as input. hclust 
doesn't give you a partition but you can generate one from it using 
cutree.
BTW, rather use "<-" than "=".

Best wishes,
Christian
