### Examples

    data(macaca)
    pro1 <- procuste(macaca$xy1, macaca$xy2, scal = FALSE)
    pro2 <- procuste(macaca$xy1, macaca$xy2)

    if(adegraphicsLoaded()) {

      g2 <- s.match(pro1$tabX, pro1$rotY, plab.cex = 0.7, plot = FALSE)
      g3 <- s.match(pro1$tabY, pro1$rotX, plab.cex = 0.7, plot = FALSE)
      g4 <- s.match(pro2$tabY, pro2$rotX, plab.cex = 0.7, plot = FALSE)
      G <- ADEgS(c(g1, g2, g3, g4), layout = c(2, 2))

    } else {
