transNode {TreeSummarizedExperiment} | R Documentation

## Transfer between node number and node label

### Description

`convertNode` does the transformation between the number and the label of a node on a tree

### Usage

    transNode(tree, node, use.alias = FALSE, message = FALSE)

    convertNode(tree, node, use.alias = FALSE, message = FALSE)

### Arguments

`tree` | A phylo object
`node` | A character or numeric vector representing tree node label(s) or tree node number(s)
`use.alias` | A logical value, TRUE or FALSE. This is an optional argument that only requried when the input `node` is a numeric vector. The default is FALSE, and the node label would be returned; otherwise, the alias of node label would be output. The alias of node label is created by adding a prefix `"alias_"` to the node number.
`message` | A logical value, TRUE or FALSE. The default is FALSE. If TRUE, message will show when a tree have duplicated labels for some internal nodes.

### Value

a vector

### Examples

    library(ggtree)

    data(tinyTree)

    ggtree(tinyTree, branch.length = 'none') +
    geom_text2(aes(label = label), hjust = -0.3) +
    geom_text2(aes(label = node), vjust = -0.8,
    hjust = -0.3, color = 'blue')

    #check whether the node number and node label are matched
    convertNode(tinyTree, node = c(11, 2, 4, 15))

    convertNode(tree = tinyTree, node = c("Node_16", "Node_11"))
    convertNode(tree = tinyTree, node = c("alias_16", "alias_11"))
