### Examples

    data(coleo)
    op <- par(no.readonly = TRUE)
    coleo.fuzzy <- prep.fuzzy.var(coleo$tab, coleo$col.blocks)
    fca1 <- dudi.fca(coleo.fuzzy, sca = FALSE, nf = 3)
    par(mfrow = c(3,3))
    indica <- factor(rep(names(coleo$col), coleo$col))
    for (j in levels(indica)) s.distri (fca1$l1,
        coleo$tab[,which(indica==j)], clab = 1.5, sub = as.character(j),
        cell = 0, csta = 0.5, csub = 3,
        label = coleo$moda.names[which(indica == j)])
    par(op)
    par(mfrow = c(1,1))
