In combinIT: A Combined Interaction Test for Unreplicated Two-Way Tables

#'
#' Impurity data in a chemical product (IDCP).
#'
#' This data were collected in an experiment to assess the impurity present in a chemical product.
#' The impurity is affected by two factors: pressure and temperature. Montgomery (2001, p. 193)
#' analyzed the data by using the Tukey single-degree-of-freedom test
#' and concluded that there is no evidence of interaction.
