#' @title Network of experiment to evaluate Wheat varieties on several years (2005-2010).
#' @description
#' The data set consists of measurements of wheat yields from a network of field experiments
#' designed to evaluate and compare performances of different varieties or varietal mixtures.
#' This extract consists of 113 different experiments corresponding to 54 different places and 6 years (2005 to 2010).
#' 80 varieties (v1 to v80) or varietal mixtures where compared.
#' TODO : CHECK The experimental designs used are complete random block designs  TODO : CHECK
#' The number of repetitions for a variety in each experiment varies from 2 to 6 (n_blocs).
