gl.drop.ind: Removes specified individuals from a genlight object

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

Removes specified individuals from a genlight object

Description

The script, having deleted individuals, optionally identifies resultant monomorphic loci or loci with all values missing and deletes them (using gl.filter.monomorphs.r). The script also optionally recalculates statistics made redundant by the deletion of individuals from the dataset.

The script returns a genlight object with the individuals deleted and, optionally, the recalculated locus metadata.

#' See more about data manipulation in the [tutorial](http://georges.biomatix.org/storage/app/media/uploaded-files/tutorial4dartrdatamanipulation22-dec-21-3.pdf).

Usage

gl.drop.ind(x, ind.list, recalc = FALSE, mono.rm = FALSE, verbose = NULL)

Arguments

x	Name of the genlight object containing SNP genotypes [required].
ind.list	A list of individuals to be removed [required].
recalc	Recalculate the locus metadata statistics [default FALSE].
mono.rm	Remove monomorphic loci [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 or as specified using gl.set.verbosity].

Value

A genlight object with the reduced data
