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

Usage

utils.recalc.freqhomsnp(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].

Value

The modified genlight object.

Details

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

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