This function was designed to add a color bar to a plot created by plotBranchbyTrait
. A color bar can be added by clicking on a location within the plot (when prompt=TRUE
) or by setting prompt=FALSE
and supplying x & y coordinates for the object.
The function is also used internally by S3 methods plot.contMap
and plot.densityMap
, as well as by errorbar.contMap
.
