Creates a phylogenetic heat map

Description

Functions creates a multivariate phylogenetic heatmap.

Usage

1
phylo.heatmap(tree, X, fsize=1, colors=NULL, standardize=FALSE, ...)

Arguments

tree

an object of class "phylo".

X

a matrix containing data for multiple continuous characters in which rownames correspond to the tip labels of the tree.

fsize

an integer or vector of length 3 containing the font size for the tip labels, the trait labels, and the legend text. (If a single integer is supplied, then the value will be recycled.)

colors

a vector of colors to be passed to image. Can be a function call (e.g., heat.colors(n=200)[200:1]).

standardize

a logical value indicating whether or not to standardize each column of X to have the same variance & mean prior to analysis.

...

optional arguments. So far these include: legend, a logical value indicating whether or not to plot a figure legend (defaults to legend=TRUE); labels, a logical value indicating whether or not to plot trait labels (defaults to labels=TRUE); split, a numeric vector indicating the fraction of the horizontal dimension to use for the tree & heatmap, respectively (defaults to split=c(0.5,0.5)); xlim, ylim, & mar, defined as in par; and ftype, lwd, and pts as defined in plotSimmap.

Value

Function creates a plot.
