    data(rhone)
    dd1 <- dudi.pca(rhone$tab, nf = 2, scann = FALSE)
    rh1 <- reconst(dd1, 1)
    rh2 <- reconst(dd1, 2)
    par(mfrow = c(4,4))
    par(mar = c(2.6,2.6,1.1,1.1))
    for (i in 1:15) {
        plot(rhone$date, rhone$tab[,i])
        lines(rhone$date, rh1[,i], lty = 2)
        lines(rhone$date, rh2[,i], lty = 1)
        scatterutil.sub(names(rhone$tab)[i], 2, "topright")
