#' @description
#' Example phenotypic and molecular marker data on a population of six-row barley lines.
#'
#' @details
#'
#' This dataset includes phenotypic observations and realized molecular marker genotypes for 245 barley
#' lines. Phenotypic observations were recorded for four traits, and the population was genotyped with
#' 742 SNP markers. The data formats are described below:
#'
#' @format A dataset with four objects:
#'
#' \describe{
#'   \item{\code{phenos}}{A \code{data.frame} with 245 rows and 5 columns of phenotypic observations of
#'   four traits on 245 barley lines. Some lines have missing data.}
#'
#'   \item{\code{genos}}{A \code{matrix} of realized molecular marker genotypes for 245 barley lines
#'   and 742 SNP markers. Genotypes are coded as \code{1} for homozygous first allele, \code{0} for heterozygous,
#'   and \code{-1} for homozygous second allele.}
#'
#'   \item{\code{map}}{A \code{data.frame} with 742 rows and 3 columns containing genetic map positions
#'   of the 742 SNP markers. The first column contains the marker name, the second column the chromosome,
#'   and the third column the genetic position.}
#'
#'   \item{\code{crosses}}{A \code{data.frame} with 186 rows and 2 columns containing specific combinations
#'   of two parents for prospective breeding crosses.}
#'
#'  }
