tab: Access allele counts or frequencies

Description Usage Arguments Value Examples

Description

This accessor is used to retrieve a matrix of allele data. By default, a matrix of integers representing allele counts is returned. If freq is TRUE, then data are standardised as frequencies, so that for any individual and any locus the data sum to 1. The argument NA.method allows to replace missing data (NAs). This accessor replaces the previous function truenames as well as the function makefreq.
