random.dag: Generate random DAGs

In sparsebnUtils: Utilities for Learning Sparse Bayesian Networks

Description

Generate a random DAG with fixed number of edges.

Usage

random.dag(nnode, nedge, FUN = NULL, permute = TRUE)

Arguments

nnode	Number of nodes in the DAG.
nedge	Number of edges in the DAG.
FUN	Optional function to be used as a random number generator.
permute	If TRUE, order of nodes will be randomly permuted. If FALSE, output will be ordered according to its topological sort, i.e. with a lower-triangular adjacency matrix.

Details

FUN can be any function whose first argument is called n. This allows for both random and deterministic outputs.

Value

An (weighted) adjacency matrix.
