Label splits
Labels the edges associated with each split on a plotted tree.
LabelSplits(tree, labels = NULL, unit = "", ...)
tree |
A tree of class |
labels |
Named vector listing annotations for each split. Names
should correspond to the node associated with each split; see
|
unit |
Character specifying units of |
... |
Additional parameters to |
As the two root edges of a rooted tree denote the same split, only the
rightmost (plotted at the bottom, by default) edge will be labelled.
If the position of the root is significant, add a tip at the root using
AddTip().
LabelSplits() returns invisible(), after plotting labels on
each relevant edge of a plot (which should already have been produced using
plot(tree)).
Calculate split support: SplitFrequency()
Colour labels according to value: SupportColour()
