#' yields.unstacked: Unstacked Yields Data
#'
#' This data is from a crop experiment where the crops were grown in three
#' different soil types, and the yield was taken from 10 randomly chosen fields
#' per soil type. This is the unstacked version of the data, with one column
#' for each soil type.
#'
#' @format A data frame with 10 observations (rows) and 3 variables (columns).
