Description

unionLeaf list the leaf nodes that are the desendants of (at least one) specified nodes.

Usage

unionLeaf(tree, node)

Arguments

tree	A phylo object.
node	A numeric or character vector. It specifies internal nodes that are changed to leaves via their node labels or numbers.

Value

A phylo object.

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)))
