data(rhone)
pca1 <- dudi.pca(rhone$tab, nf = 2, scann = FALSE)
rh1 <- reconst(pca1, 1)
rh2 <- reconst(pca1, 2)
par(mfrow = c(4,4))
par(mar = c(2.6,2.6,1.1,1.1))
for (i in 1:15) {
    plot(rhone$date, rhone$tab[,i])
    lines(rhone$date, rh1[,i], lwd = 2)
    lines(rhone$date, rh2[,i])
    ade4:::scatterutil.sub(names(rhone$tab)[i], 2, "topright")
