catnet (version 1.09.4)

cnOrder-method: Network Node Order

Description

The function returns an order of the nodes of a network that is compatible with its parent structure.

Usage

cnOrder(object)

Arguments

object

a catNetwork or a list of node parents.

Value

• a list of node indices.

Details

An order is compatible with the parent structure of a network if each node has as parents only nodes appearing earlier in that order. That such an order exists is guaranteed by the fact that every catNetwork is a DAG (Directed Acyclic Graph). The result is one order out of, eventually, many possible.

Examples

cnet <- cnRandomCatnet(numnodes=20, maxParents=3, numCategories=2)
  cnOrder(object=cnet)
