gl.drop.loc {dartR.base}

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 = NULL, last = 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

First of a range of loci to be deleted [required, if loc.list not specified].

last

Last of a range of loci to be deleted [if not specified, last 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
