#' farms0: Size of Plants at Five Different Locations (subset)

#' This data set is a subsample of the \code{\link{farms}} data set. In this
#' subset there are different numbers of data from each farm. See details for
#' description of the original data set.

#' @details
#'
#' The size of plants has been measured on 24 farms in five different
#' locations.There is various Nitrogen content in the soil within each of the
#' 24 farms. This data set illustrates spatial pseudo-replication, since the
#' five measurements made on each farm are probably dependent, coming from the
#' same farm.
#'
#' The original data set is the same data set as in `The R book`, but with
#' different column names.
