order4nbn: topological order of a /nbn/

In rbmn: Handling Linear Gaussian Bayesian Networks

topological order of a /nbn/

Description

returns one of the orders of the nodes such as the parents of any node are less ranked than it when is.null(ord). If not check that the proposed order is either a right permutation (is.numeric(ord)) or a vector of node names providing a topological order (is.character(ord)).

Usage

order4nbn(nbn, ord=NULL)

Arguments

nbn	nbn object for which the order must be computed.
ord	NULL or an order to test as a permutation or a vector of names.

Details

When !is.null(ord) the order must be an order, if not an error is issued.

Value

a permutation vector of the nodes of the /nbn/ or a named list with the nodes not having their parents before them.

Examples

 names(rbmn0nbn.04)[order4nbn(rbmn0nbn.04)];
