caugi (version 1.1.0)

children: Get children of nodes in a caugi

Description

Get children of nodes in a graph (nodes with directed edges pointing OUT from the target nodes). This is equivalent to neighbors(cg, nodes, mode = "out").

Usage

children(cg, nodes = NULL, index = NULL)

Value

Either a character vector of node names (if a single node is requested) or a list of character vectors (if multiple nodes are requested).

Arguments

cg

A caugi object.

nodes

A character vector of node names.

index

A vector of node indexes.

  A %-->% B,
  B %-->% C,

children(cg, index = 2) # "C"
children(cg, "B") # "C"
children(cg, c("B", "C"))
