EcoGenetics (version 1.2.1-5)

eco.alfreq: Allelic frequency histograms for an ecogen genetic data frame

Description

This program computes the frequency of each allele and plots a histogram for the number of alleles with a given frequency. The distribution is expected to be L-shaped under mutation-drift equilibrium. When a factor is given, the program plots a histogram for each group.

Usage

eco.alfreq(eco, grp = NULL)

Arguments

eco

Object of class "ecogen".

grp

Optional factor (column of the S slot) for plots by group.
