## human mitochondrial DNA restriction data

### Description

This data set gives the frequencies of haplotypes of mitochondrial DNA restriction data in ten populations all over the world.
It gives also distances among the haplotypes.

### Usage

    data(humDNAm)

### Format

`humDNAm` is a list of 3 components.

distances
  is an object of class `dist` with 56 haplotypes. These distances are computed by counting the number of differences in restriction sites between two haplotypes.
samples
  is a data frame with 56 haplotypes, 10 abundance variables (populations). These variables give the haplotype abundance in a given population.
structures
  is a data frame with 10 populations, 1 variable (classification). This variable gives the name of the continent in which a given population is located

### Examples

    data(humDNAm)
    dpcoahum <- dpcoa(humDNAm$samples, sqrt(humDNAm$distances), scan = FALSE, nf = 2)
    plot(dpcoahum, csize = 1.5)
