plot.phylog.prcomp: Plot a phylog.prcomp object

In PHYLOGR: Functions for Phylogenetically Based Statistical Analyses

Description

Plots histogram of the eigenvalues for simulated data as returned from a phylog.prcomp object; with vertical bars indicates the values from the original (”real”) data (the one with sim.counter=0).

Usage

## S3 method for class 'phylog.prcomp'
plot(x, ...)

Arguments

x	an object of class phylog.prcomp such as can be obtained from a previous call to prcomp.phylog.
...	other parameters to be passed to through to plotting functions (currently not used).

WARNING

These histograms are in the spirit of the 'naive' p-values returned from summary.phylog.prcomp; see Details for summary.phylog.prcomp
