      col=NULL, nodeinfo=FALSE, cases="obs", new=TRUE)

Arguments

cluster	object of class hclust or twins.
data	clustered dataset for hclust application.
cex	size of text, par parameter.
pch	shape of symbol at leaves, par parameter.
size	size in cex units of symbol at leaves.
col	vector of colors from hsv, rgb, etc, or if NULL, then use rainbow.
nodeinfo	if TRUE, add a line at each node with number of observations included in each leaf.
cases	label for type of observations.
