### Examples

    data(trichometeo)
    faulog <- log(trichometeo$fau + 1)
    pca1 <- dudi.pca(trichometeo$meteo, scan = FALSE)
    niche1 <- niche(pca1, faulog, scan = FALSE)

    if(adegraphicsLoaded()) {
      g1 <- s.distri(niche1$ls, faulog, plab.cex = 0.6, ellipseSize = 0, starSize = 0.3, plot = FALSE)
      g2 <- s.arrow(7 * niche1$c1, plab.cex = 1, plot = FALSE)
      G <- superpose(g1, g2, plot = TRUE)

    } else {
      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)
