Description

Graph a hierarchical cluster tree of class twins or hclust using colored symbols at observations.

object of class hclust or twins.

data

cex

size of text, par parameter.

pch

shape of symbol at leaves, par parameter.

size

nodeinfo

if TRUE, add a line at each node with number of observations included in each leaf.

cases

label for type of observations.
