addLabel: add labels to nodes of a tree

In TreeSummarizedExperiment: TreeSummarizedExperiment: a S4 Class for Data with Tree Structures

Description

addLabel adds labels to the node of a tree (phylo object)

Usage

addLabel(tree, label = NULL)

Arguments

tree	A phylo object
label	A character vector as the label of tree. The label is passed to nodes that are sorted by their node number in ascending order. The default is NULL, and nodes are labeled by using their node numbers (convert node numbers from numeric values to characters)

Value

a phylo object

Examples

 
data(tinyTree)
library(ggtree)

# PLOT tree
# The node labels are in orange texts and the node numbers are in blue
ggtree(tinyTree,branch.length = 'none')+
    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)

# change labels
nodes <- showNode(tree = tinyTree, only.leaf = FALSE)
tt <- addLabel(tree = tinyTree, label = LETTERS[nodes])

ggtree(tt, branch.length = 'none')+
    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)
