markChanges: Add marked changes to a plotted tree with mapped discrete character
Description
This function adds the reconstructed changes to a plotted tree with a stochastically mapped discrete character.
Usage
markChanges(tree, colors=NULL, cex=1, lwd=2, plot=TRUE)
Arguments
tree
an object of class "simmap"
.
colors
a named vector of colors used to plot the stochastically mapped character on the tree.
cex
expansion factor for line height.
plot
logical value indicating whether the changes should be plotted or not.
Value
This function returns (invisibly) a matrix containing the x & y coordinates of the marked changes.
