#' Wear of rubber-covered fabrics
#' 
#' The Fabric dataset contains the results from an experiment that used a Latin square design to assess the wear characteristics of four different rubber-covered fabrics. The column factor of the square corresponds to four different runs, and the row factor corresponds to four positions on the testing machine that was used to generate wear under simulated natural conditions.
