randomNodeGraph: Generate Random Graph with Specified Degree Distribution
Description
randomNodeGraph generates a random graph with the specified
degree distribution. Self-loops are allowed. The resultant graph is
directed (but can always be coerced to be undirected).
Usage
randomNodeGraph(nodeDegree)
Arguments
nodeDegree
A named integer vector specifying the node degrees.
Value
An instance of the graphNEL class. The graph is directed.
Details
The input vector must be named, the names are taken to be the names of
the nodes. The sum must be even (there is a theorem that says we
require that to construct a graph). Self-loops are allowed, although
patches to the code that make this a switchable parameter would be
welcome.
