utils.recalc.freqhets {dartR}

A utility script to recalculate the frequency of the heterozygous SNPs by locus after some populations have been deleted

Description

The locus metadata supplied by DArT has FreqHets included, but the frequency of the heterozygotes will change when some individuals are removed from the dataset.

Usage

utils.recalc.freqhets(x, verbose = NULL)

Arguments

x

Name of the genlight object containing the SNP data [required].

verbose

Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default 2].

Details

This script recalculates the FreqHets and places these recalculated values in the appropriate place in the genlight object.

Note that the frequency of the homozygote reference SNPS is calculated from the individuals that could be scored.

Value

The modified genlight object.
