gl.drop.loc: Removes specified loci from a dartR genlight object

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

Removes specified loci from a dartR genlight object

Description

This function deletes individuals and their associated metadata.

The script returns a dartR genlight object with the retained loci. The script works with both genlight objects containing SNP genotypes and Tag P/A data (SilicoDArT).

Usage

gl.drop.loc(
  x,
  loc.list = NULL,
  first_tmp = NULL,
  last_tmp = NULL,
  verbose = NULL
)

Arguments

x	Name of the genlight object [required].
loc.list	A list of loci to be deleted [required, if loc.range not specified].
first_tmp	First of a range of loci to be deleted [required, if loc.list not specified].
last_tmp	Last of a range of loci to be deleted [if not specified, last_tmp locus in the dataset].
verbose	Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress but not results; 3, progress and results summary; 5, full report [default 2 or as specified using gl.set.verbosity].

Value

A reduced dartR genlight object
