hier_match: Match default and original node labels

Description

This function returns a data.table that maps original and default codes.

Usage

hier_match(tree, nodes = NULL, inputs = "orig")

Value

a data.table with the following columns:

• "orig": the original node names

• `"default": the standardized names

• "is_bogus": TRUE if the code is a "bogus" (duplicated) node.

Arguments

tree

an input derived from hier_create() or hier_convert()

nodes

NULL or a character vector specifying either original node names or standardized default codes. If NULL, the information is returned for all nodes.

inputs

(character) specifies what kind of node names are provided in argument nodes. Allowed choices are:

• "orig": argument nodes refers to original node names

• "default": argument nodes refers to standardized default codes

Examples

h <- hier_create(root = "Tot", nodes = letters[1:5])
h <- hier_add(h, root = "a", nodes = "a0")
h2 <- hier_convert(tree = h, as = "dt")
hier_match(tree = h, nodes = c("a", "b"), inputs = "orig")
hier_match(tree = h2, nodes = c("01", "02"), inputs = "default")
