##' @title Heavy metal biomonitoring in Galicia
##' @description This data-set relates to two studies on lead concentration in moss samples,
##' in micrograms per gram dry weight, collected in Galicia, norther Spain. The data
##' are from two surveys, one conducted in October 1997 and on in July 2000.
##' The variables are as follows:
##' \itemize{
##'  \item x x-coordinate of the spatial locations.
##'  \item y y-coordinate of the spatial locations.
##'  \item lead lead concentration.
##'  \item survey year of the survey (either 1997 or 2000).
