## Distance Matrices

### Description

This data set gives 3 matrices about geographical, genetic and anthropometric distances.

### Usage

    data(yanomama)

### Format

`yanomama` is a list of 3 components:

geo

  is a matrix of 19-19 geographical distances

gen

  is a matrix of 19-19 SFA (genetic) distances

ant

  is a matrix of 19-19 anthropometric distances

### Examples

        data(yanomama)
        gen <- quasieuclid(as.dist(yanomama$gen)) # depends of mva
        ant <- quasieuclid(as.dist(yanomama$ant)) # depends of mva
        par(mfrow = c(2,2))
        plot(gen, ant)
        t1 <- mantel.randtest(gen, ant, 99);
        plot(t1, main = "gen-ant-mantel") ; print(t1)
        t1 <- procuste.rtest(pcoscaled(gen), pcoscaled(ant), 99)
        plot(t1, main = "gen-ant-procuste") ; print(t1)
        t1 <- RV.rtest(pcoscaled(gen), pcoscaled(ant), 99)
        plot(t1, main = "gen-ant-RV") ; print(t1)
