#' Subset of individuals and SNPs from Uitdewilligen et al (2013).
#'
#' A list containing a matrix of reference counts, a matrix of total counts, and the ploidy level (4) of the species.
#' This is a subset of the data from Uitdewilligen et al (2013).
#'
#' @format A list containing three objects. Two matrices and a numeric scalar:
#' \describe{
#'   \item{refmat}{A matrix of read counts containing the reference allele. The rows index the individuals and the columns index the SNPs.}
#'   \item{sizemat}{A matrix of the total number of read counts. The rows index the individuals and the columns index the SNPs.}
#'   \item{ploidy}{The ploidy level of the species (just 4).}
#' }

#' GBS data from Shirasawa et al (2017)
#'
#' Contains counts of reference alleles and total read counts from the GBS data of Shirasawa et al (2017) for
#' the three SNPs used as examples in Gerard et. al. (2018).
#'
#' @format A \code{tibble} with 419 rows and 4 columns:
#' \describe{
#'     \item{id}{The identification label of the individuals.}
#'     \item{snp}{The SNP label.}
#'     \item{counts}{The number of read-counts that support the reference allele.}
#'     \item{size}{The total number of read-counts at a given SNP.}
#' }
