Plots a tree with error bars around divergence times (nodes).
plotTree.errorbars(tree, CI, ...)an object of class "phylo".
confidence intervals around internal nodes of the tree, measured in time since the present.
optional arguments to be passed to plotTree.
Plots a tree with error bars around internal nodes..
The matrix CI show contain (in rows) the lower & upper confidence bounds in time since the present.
Optional arguments specific to the error bar plot include gridlines, bar.lwd,cex (for the points plotted at nodes), and bar.col.
