    ss <- sample(1:150, 10 )
    hc1 <- iris[ss,-5] %>% dist %>% hclust("com")
    hc2 <- iris[ss,-5] %>% dist %>% hclust("single")
    dend1 <- as.dendrogram(hc1)
    dend2 <- as.dendrogram(hc2)

    cor_FM_index(dend1, dend2, k = 2)
    cor_FM_index(dend1, dend2, k = 3)
    cor_FM_index(dend1, dend2, k = 4)
