#' screeningResult class
#'
#' A result of procedure for snp clumping produced by \code{\link{screen_snps}}
#'
#' @details Always a named list of eight elements
#' \enumerate{
#' \item \code{X} numeric matrix, consists of snps that passed screening
#' \item \code{y} numeric vector, phenotype
#' \item \code{X_info} data.frame, SNP info from .map file
#' \item \code{pVals} numeric vector, p-values from marginal tests for each snp
#' \item \code{numberOfSnps} numeric, total number of SNPs in .raw file
#' \item \code{selectedSnpsNumbers} numeric vector, which rows of \code{X_info}
#' data.frame are related to snps that passed screening
#' \item \code{pValMax} numeric, p-value used in screening procedure
#' \item \code{phenotypeInfo} data.frame, additional information about observations
#' provied in \code{\link{phenotypeData}} object
#' }
