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 |
