data(trichometeo)
faulog <- log(trichometeo$fau + 1)
pca1 <- dudi.pca(trichometeo$meteo, scan = FALSE)
niche1 <- niche(pca1, faulog, scan = FALSE)
s.label(niche1$ls, clab = 0)
s.distri(niche1$ls, faulog, clab = 0.6, add.p = TRUE, 
    cell = 0, csta = 0.3)
s.arrow(7 * niche1$c1, clab = 1, add.p = TRUE)
