#' @description
#' \pkg{rYWAASB} performs a new ranking algorithm based on a
#' "Y*WAASB" biplot generated by the 'metan' package which is
#' used in MET(Multi-Environmental Trials).
#' This package effectively distinguishes the top-ranked genotypes
#' based on a given trait (e.g. grain yield or any other trait
#' in agricultural experiments) and the "WAASB" index in the
#' Genotype-by-environment interaction effect studies.
#' Note: Fortunately, this package can impute missing
#' observations and computes them, eliminating any concerns
#' about their presence in the data set. A complete guide
#' may be found at: <https://github.com/abeyran/rYWAASB/issues>
