add_ci {phangorn}

Draw Confidences Intervals on Phylogenies

Description

These are low-level plotting commands to draw the confidence intervals on the node of a tree as rectangles with coloured backgrounds or add boxplots to ultrametric or tipdated trees.

Usage

add_ci(tree, trees, col95 = "#FF00004D", col50 = "#0000FF4D",
  height = 0.7, legend = TRUE, ...)

add_boxplot(tree, trees, ...)

Arguments

tree

a phylogenetic tree to which the confidences should be added.

trees

phylogenetic trees, i.e. an object of class 'multiPhylo'

col95

colour used for the 95 red.

col50

colour used for the 50 blue.

height

the height of the boxes.

legend

a logical value.

...

arguments passed to other functions, legend or bxp.

Details

All trees should to be rooted, either ultrametric or tip dated.
