#' Effects of nitrogen fertiliser on yields of varieties of rice
#' 
#' The Rice dataset contains data from an experiment that studied 
#' the effect of three levels of nitrogen fertilizer on the yields 
#' of six varieties of rice. The experiment used a strip-plot design. 
#' This is a replicated row and column design. Each replicate had three
#' columns and six rows. Within each replicate, the nitrogen levels 
#' were randomized onto the columns, and the varieties were
#' randomized onto the rows.The response variable is the yield of rice.
