add.simmap.legend

Add legend to stochastically mapped tree

This function adds a legend (by default, interactively) to a plotted stochastic character mapped tree.

add.simmap.legend(leg=NULL, colors, prompt=TRUE, vertical=TRUE, ...)

`leg`	states for the discrete character in the order of `colors`.
`colors`	colors for the legend in the order of `leg`, or, if `leg=NULL`, named vector of colors in which `names(colors` are the states of the mapped discrete character.
`prompt`	logical value indicating whether the location of the legend should be obtained interactively (i.e., by clicking in the plotting area).
`vertical`	logical value indiciating whether to plot the legend vertically (if `TRUE`) or horizontally.
`...`	optional arguments including: `x` x-coordinate of the legend (if `prompt=FALSE`); `y` y-coordinate of the legend; and `shape` which can be `shape="square"`, the default, or `shape="circle"`.
