#' @title Description of the testdata
#' @name testdata
#' @docType data
#' @description The data set contains paternal haplotypes, maternal LD and
#' genetic map positions that are required to calculate the covariance between
#' pairs of markers.
#' \describe{
#' The raw data can be downloaded at the source given below. Then,
#' executing the following R code leads to the data that have been provided as
#' \code{testdata.RData}.
#' \item{H.sire}{(2N x p) haplotype matrix for sires for all chromosomes
#' (2 lines per sire)}
#' \item{matLD}{(p x p) matrix of maternal LD between pairs of p markers;
#' matrix is block diagonal in case of multiple chromosomes}
#' \item{pos.chr}{list of vectors of genetic map positions per chromosome}
#' }
#' @source The data are available from RADAR \doi{10.22000/280}.
