vt_add_nodes

Description

add (sub)nodes to a node generated by vt_create_node or returned from vt_add_nodes

Usage

  codes = NULL)

Arguments

node

a node object

refnode

name of the reference node

node_names

new node names

colors

optionally a vector of colors matching the length of node_names

weights

optionally a vector of weights matching the length of node_names

codes

optionally a vector of short labels matching the length of node_names

Value

a Node object

Examples

n <- vt_create_node("Total")
n <- vt_add_nodes(n, refnode="Total",node_names=c("Asia","Europe"), colors=c("red","blue"))
n <- vt_add_nodes(n, refnode="Asia",node_names=c("China","Thailand"),
  weights=c(0.5, 0.8), codes=c("CN","TH"))
n <- vt_add_nodes(n, refnode="Europe",node_names=c("Netherlands","Austria"),
  weights=c(0.9, 1.1), codes=c("NL","AT"))
print(n, "weight", "code", "color")
