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.

Value

Nothing. Function is called for adding to a plot.

Details

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

Examples

data("Laurasiatherian")
dm <- dist.hamming(Laurasiatherian)
tree <- upgma(dm)
set.seed(123)
trees <- bootstrap.phyDat(Laurasiatherian,
                          FUN=function(x)upgma(dist.hamming(x)), bs=100)
tree <- plotBS(tree, trees, "phylogram")
add_ci(tree, trees)

plot(tree, direction="downwards")
add_boxplot(tree, trees, boxwex=.7)
