The locus metadata supplied by DArT does not have MAF included, so it is calculated and added to the locus.metadata by this script. The minimum allele frequency will change when some individuals are removed from the dataset. This script recalculates the MAF and places these recalculated values in the appropriate place in the genlight object.

Usage

utils.recalc.maf(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 dataset.
