    tax <- as.taxo(taxo.eg[[1]])
    tax.phy <- taxo2phylog(as.taxo(taxo.eg[[1]]))
    par(mfrow = c(1,2))
    plot.phylog(tax.phy, clabel.l = 1.25, clabel.n = 1.25, f = 0.75)
    plot.phylog(taxo2phylog(as.taxo(taxo.eg[[1]][sample(15),])),
     clabel.l = 1.25, clabel.n = 1.25, f = 0.75)
    par(mfrow = c(1,1))
