data(monde84)
X <- cbind.data.frame(lpib = log(monde84$pib), monde84$croipop)
Y <- cbind.data.frame(lmorta = log(monde84$morta), 
    lanal = log(monde84$anal + 1), rscol = sqrt(100 - monde84$scol))
pcaY <- dudi.pca(Y, scan = FALSE)
pcaiv1 <- pcaiv(pcaY, X0 <- scale(X), scan = FALSE)
sum(cor(pcaiv1$l1[,1], Y0 <- scale(Y))^2)
