phenogram: Plot phenogram (traitgram)

Description

Function plots a traitgram, that is, a projection of the phylogenetic tree in a space defined by phenotype (on the y axis) and time (on the x). If a discrete character is mapped on the tree this will also be plotted.

Usage

phenogram(tree,x,fsize=1.0,ftype="reg",colors=NULL)

Arguments

tree

an object of class "phylo", with or without a mapped discrete character.

x

a vector containing the states at the tips or the states at all the tips and the internal nodes of the tree.

fsize

relative font size for tip labels.

ftype

font type - options are "reg", "i" (italics), "b" (bold), or "bi" (bold-italics).

colors

colors for plotting the mapped character (if available) in tree.

Value

• plots a traitgram, optionally with a mapped discrete character.

Examples

tree<-rcoal(n=20)
  x<-fastBM(tree)
  phenogram(tree,x)
