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

Hello,
I am using the dunn metric, but something is wrong and I dont understand
what or what that this error mean. Please can you help me with this?
The instructions are:
#Indice de Dunn
disbupa=dist(bupa[,1:6])
a=hclust(disbupa)
cluster.stats(disbupa,a,bupa[,7])$dunn
And the error is:
Error in max(clustering) : invalid 'type' (list) of argument
thank you so much.
