Plot quartet on tree topologies

Description

Draws a tree, highlighting the members of a specified quartet in colour.

Usage

PlotQuartet(tree, quartet, overwritePar = TRUE, caption = TRUE, ...)

Arguments

tree	A tree of class phylo, or a list of such trees. The first member of tree will be considered the "reference" tree.
quartet	A vector of four integers, corresponding to numbered leaves on the tree; or a character vector specifying the labels of four leaves.
overwritePar	Logical specifying whether to use existing mfrow and mar parameters from par() (FALSE), or to plot trees side-by-side in a new graphical device (TRUE).
caption	Logical specifying whether to annotate each plot to specify whether the quartet selected is in the same or a different state to the reference tree.
...	Additional parameters to send to plot().

Value

PlotQuartet() returns invisible(), having plotted a tree in which the first two members of quartet are highlighted in orange, and the second two highlighted in blue.

par(oPar)
