### Examples

    data(zealand)

    d0 = mat2dist(as.matrix(zealand$road))
    d1 = cailliez (d0)
    d2 = lingoes(d0)
    s.label(zealand$xy,lab=as.character(1:13),neig=zealand$neig)
    par(mfrow = c(2,2))
    library(mva)
        s.label(cmdscale(dist(zealand$xy)),lab = as.character(1:13),
         neig = zealand$neig, sub = "Distance canonique", csub = 2)
        s.label(cmdscale(d0), lab = as.character(1:13), neig = zealand$neig,
            sub = "Distance routière", csub = 2)
        s.label(cmdscale(d1), lab = as.character(1:13), neig = zealand$neig,
            sub = "Distance routière / Cailliez", csub = 2)
        s.label(cmdscale(d2), lab = as.character(1:13), neig = zealand$neig,
            sub = "Distance routière / Lingoës", csub = 2)
