StatGraphs
 a package for graphs used in statistical models
Bigraph
 a graph with bidirected edges and no multiple edges
bigraph
 create a bigraph
bigraph(...,EntryMode=>...)
 optional input, accepts 'auto', 'edges', or 'neighbors'
bigraph(...,Singletons=>...)
 optional input, accepts the list of isolated vertices in a bigraph
bigraph(MixedGraph)
 extract the bigraph component of a mixed graph
children(MixedGraph,Thing)
 return the children of a vertex of a mixed graph
collateVertices
 convert a mixed graph into a new mixed graph where each component subgraph has the same set of vertices
descendants(MixedGraph,Thing)
 return the descendants of a vertex of a mixed graph
digraph(MixedGraph)
 extract the digraph component of a mixed graph
forefathers(MixedGraph,Thing)
 return the forefathers of a vertex of a mixed graph
graph(MixedGraph)
 convert mixed graph to a hash table
indexLabelGraph(MixedGraph)
 relabel the vertices of a mixed graph according to their indices, indexed from 0
isCyclic(MixedGraph)
 check whether a mixed graph contains a directed cycle
isLoopless
 check whether a graph contains a loop
isSimple(MixedGraph)
 check whether a mixed graph is simple
MixedGraph
 a graph that has undirected, directed and bidirected edges
mixedGraph
 create a mixed graph from a combination of undirected graph, digraph and bigraph
neighbors(MixedGraph,Thing)
 return the neighbors of a vertex of a mixed graph
net(MixedGraph)
 print a mixed graph as a net
nondescendants(MixedGraph,Thing)
 return the nondescendents of a vertex of a mixed graph
nonneighbors(MixedGraph,Thing)
 return the neighbors of a vertex of a mixed graph
parents(MixedGraph,Thing)
 return the parents of a vertex of a mixed graph
partitionLMG
 partition the vertices of a loopless mixed graph into adjacent to undirected edges and adjacent to bidirected edges
toString(MixedGraph)
 print a mixed graph as a string
undirectedGraph
 extract the undirected graph component of a mixed graph
vertices(MixedGraph)
 create a union of all vertices of a mixed graph
