### Examples

    library(ggtree)
    data(tinyTree)
    ggtree(tinyTree, ladderize = FALSE) +
        geom_text2(aes(label = label), color = "darkorange",
               hjust = -0.1, vjust = -0.7) +
        geom_text2(aes(label = node), color = "darkblue",
                   hjust = -0.5, vjust = 0.7) +
        geom_hilight(node = 18) +
        geom_point2()

    u1 <- unionLeaf(tree = tinyTree, node = c(19, 17))
    u2 <- unionLeaf(tree = tinyTree, node = c(19, 17, 7))
    (u3 <- unionLeaf(tree = tinyTree, node = c(11, 17, 7)))
