Removes all but the specified loci from a genlight object

Description

The script returns a genlight object with the all but the specified loci deleted.

gl.keep.loc(x, loc.list = NULL, first = NULL, last = NULL, verbose = NULL)

Arguments

x	Name of the genlight object containing SNP genotypes or presence/absence data [required].
loc.list	A list of loci to be kept [required, if loc.range not specified].
first	First of a range of loci to be kept [required, if loc.list not specified].
last	Last of a range of loci to be kept [if not specified, last locus in the dataset].
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]
