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