gl.filter.excess.het: Filters excessively-heterozygous loci from a genlight object

Description

Calculates excess of heterozygosity in a genlight object and remove those loci

Usage

gl.filter.excess.het(
  x,
  Yates = FALSE,
  mono.rm = FALSE,
  recalc = FALSE,
  verbose = NULL
)

Value

Returns unaltered genlight object

Arguments

x

A genlight object containing the SNP genotypes [required].

Yates

Whether to use Yates's continuity correction [default FALSE].

mono.rm

Remove monomorphic loci after analysis is complete [default FALSE].

recalc

Recalculate the locus metadata statistics if any individuals are deleted in the filtering [default FALSE].

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].
