#' A block design for an experiment in human-computer interaction
#'
#' This is a block design to compare two methods (mouse and stylus) of drawing a map in a computer file. The design involved 12 subjects randomised in 6 days and 2 tests (morning/afternoon) within each day, across 2 rooms. The design is based on 2x2 Latin squares; see Example 7 Brien and Bailey (2006) for more details.
#'
#' @format A data frame of 24 observations on 7 factors The 7 factors included in the design are:
#' \describe{
#'   \item{Subject}{Categoric factor with levels 1-12.}
#'   \item{Day}{Categoric factor with levels 1-6.}
#'   \item{Room}{Categoric factor with levels A and B.}
#'   \item{Period}{Categoric factor with levels Morning and Afternoon.}
#'   \item{Method}{Categoric factor with levels Mouse and Stylus.}
#'   \item{Sequence}{Categoric factor with levels 1 and 2.}
#'   \item{Test}{Categoric factor with levels 1-24.}
#' }
