#' Heights of offspring of Zea mays
#'
#' A dataset containing the height of 15 pairs of the offspring of maize plants.
#'
#' @format A data frame with 15 pairs of observations and three variables:
#' \describe{
#'   \item{Pair}{Pair number, a numeric vector}
#'   \item{Cross}{Height of cross-fertilized plants, a numeric vector}
#'   \item{Self}{Height of self-fertilized plants, a numeric vector}
#' }
#' @details {
#' Darwin took 15 pairs of \emph{Zea Mays} plants, where within each pair the
#' two plants were of exactly the same age, were subjected from the first to
#' last to the same conditions, and were descended from the same parents. One
#' individual in each pair was cross-fertilized and the other was
#' self-fertilized. The heights of offspring were then measured to the nearest
#' eighth of an inch. This data set was used by Fisher (1935) to introduce the
#' idea of the randomization test with paired comparison data.
