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.

Ana Maria Aparicio.
