In jgx65/hierfstat: Estimation and Tests of Hierarchical F-Statistics

Principal coordinate analysis

Description

principal coordinates analysis as described in Legendre & Legendre Numerical Ecology

Usage

pcoa(mat,plotit=TRUE,...)

Arguments

mat	a distance matrix
plotit	Whether to produce a plot of the pcoa
...	further arguments (graphical for instance) to pass to the function

Value

valp	the eigen values of the pcoa
vecp	the eigen vectors of the pcoa (the coordinates of observations)
eucl	The cumulative euclidian distances among observations,

Examples

data(gtrunchier)
colo<-c("black","red","blue","yellow","orange","green")
pcoa(as.matrix(genet.dist(gtrunchier[,-1])),col=rep(colo,c(5,5,4,5,5,5)))
