gl.filter.heterozygosity: Filters individuals with average heterozygosity greater than...

In dartR: Importing and Analysing 'SNP' and 'Silicodart' Data Generated by Genome-Wide Restriction Fragment Analysis

Filters individuals with average heterozygosity greater than a specified upper threshold or less than a specified lower threshold

Description

Calculates the observed heterozygosity for each individual in a genlight object and filters individuals based on specified threshold values. Use gl.report.heterozygosity to determine the appropriate thresholds.

Usage

gl.filter.heterozygosity(x, t.upper = 0.7, t.lower = 0, verbose = NULL)

Arguments

x	A genlight object containing the SNP genotypes [required].
t.upper	Filter individuals > the threshold [default 0.7].
t.lower	Filter individuals < the threshold [default 0].
verbose	Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default 2, unless specified using gl.set.verbosity].

Value

The filtered genlight object.
