#' @title An example data set: electron microprobe data.
#' 
#' @description This dataset is kindly provided by Anne-Magali Seydoux-Guillaume
#' \email{anne.magali.seydoux@univ-st-etienne.fr} and has been published in 
#' Seydoux-Guillaume \emph{et al.} (2012).

#' 
#' @format 
#' A data frame with 32 observations on the following 6 variables:
#' \itemize{
#'    \item \strong{U}: U concentration (ppm)
#'    \item \strong{errU}: error on the measurement of U concentration
#'    \item \strong{Th}: Th concentration (ppm)
#'    \item \strong{ErrTh}: error on the measurement of Th concentration
#'    \item \strong{Pb}: Pb concentration (ppm)
#'    \item \strong{ErrPb}: error on the measurement of Pb concentration
#' }
#' 
#' @details The first 8 observations are group control data (more precisely, they correspond
#' to standard reference analyses). When testing if all the observations are issued
#' from a single population, the assumption is thus rejected. Removing the first 8
#' observations leads to obtain a positive answer when testing if the observations
#' come from the same population. See \code{demo(srilanka)}.
