#' @format A list of 4 data sets:
#' \describe{
#'  \item{Dataset-1}{Data frame including all SNP effects and changes in allele frequencies between cycle 2 and 5.}
#'  \item{Dataset-2}{BLUP breeding values for Acid Detergent Fiber (ADF) involving 5 generations of selection.}
#'  \item{Dataset-3}{Map file: Each line of the Map file describes a single marker and must contain at least three columns. 1: chromosome number; 2: SNP (snp id); 3: SNP position (in base-pairs (bp)).}
#'  \item{Dataset-4}{Maize Genotype (Illumina MaizeSNP50 BeadChip); an Infinium HD assay (Illumina, Inc. San Diego, CA). 
#'                   10,017 SNP markers (0,1 and 2) after filtration, distributed across the maize genome (Ganal et al.2011).}
