gl.keep.ind {dartR.base}

Removes all but the specified individuals from a dartR genlight object

Description

This script deletes all individuals apart from those listed (ind.list). Monomorphic loci and loci that are scored all NA are optionally deleted (mono.rm=TRUE). The script also optionally recalculates locus metatdata statistics to accommodate the deletion of individuals from the dataset (recalc=TRUE). The script returns a dartR genlight object with the retained individuals and the recalculated locus metadata. The script works with both genlight objects containing SNP genotypes and Tag P/A data (SilicoDArT).

Usage

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

Arguments

x

Name of the genlight object [required].

ind.list

A list of individuals to be retained [required].

recalc

If TRUE, recalculate the locus metadata statistics [default FALSE].

mono.rm

If TRUE, remove monomorphic and all NA 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 reduced dartR genlight object
