allelic.richness: Estimates allelic richness

Description

Estimates allelic richness, the rarefied allelic counts, per locus and population

Usage

allelic.richness(data,min.n=NULL,diploid=TRUE)

Arguments

data

A data frame, with as many rows as individuals. The first column contains the population to which the individual belongs, the following to the different loci

min.n

The number of alleles down to which the number of alleles should be rarefied. The default is the minimum number of individuals genotyped (times 2 for diploids)

diploid

a boolean specifying wether individuals are diploid (default) or haploid

Value

min.all

The number of alleles used for rarefaction

Ar

A table with as many rows as loci and columns as populations containing the rarefied allele counts
