In dartR.base: Analysing 'SNP' and 'Silicodart' Data - Basic Functions

Subsample loci from a genlight object

Description

A function to subsample loci at random in a genlight object with and without replacement.

Usage

gl.subsample.loc(x, n, replace = TRUE, error.check = TRUE, verbose = NULL)

Arguments

x	Name of the genlight object containing the SNP or presence/absence (SilicoDArT) data [required].
n	Number of loci to include in the subsample [default NULL]
replace	If TRUE, sampling is with replacement [default TRUE]
error.check	If TRUE, will undertake error checks on input parameters [default TRUE]
verbose	Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log; 3, progress and results summary; 5, full report [default NULL, unless specified using gl.set.verbosity]

Details

Retain a subset of loci at random, with or without replacement. Parameter n must be less than or equal to nLoc(x).

#' Set error.check = FALSE for speedy execution in simulations

Value

Returns the subsampled genlight object
