cladelabels: Add labels to subtrees of a plotted phylogeny

Description

This function adds clade labels to a plotted tree.

Usage

cladelabels(tree=NULL, text, node, offset=NULL, wing.length=NULL, cex=1)

Arguments

tree
an object of class "phylo". If not supplied, the function will obtain the last plotted phylogeny from the environmental variable last_plot.phylo.
text
desired clade label text.
node
node number for the most recent common ancestor of members of the clade.
offset
offset (as a multiplier of character width) for the label. Defaults to offset=1 if tree is supplied or offset=8 otherwise.
wing.length
length of the wings to add to the top & bottom of the label bar (in character widths).
cex
character expansion factor.

Details

This function presently works only for rightward facing plotted phylogenies - but no warning will be returned if your tree does not conform to this requirement!
