#' Sugar Processing Data
#'
#' Sugar was sampled continuously during eight hours to make
#' a mean sample representative for one "shift"
#' (eight hour period). Samples were taken during the
#' three months of operation (the so-called campaign) in
#' late autumn from a sugar plant in Scandinavia giving a
#' total of 268 samples. The sugar was sampled directly
#' from the final unit operation (centrifuge) of the process.
