validFactorClasses: Valid factor vertex classes
Description
Return matrix with labels of valid factor vertex classes
and the valid factor vertex classes. Usage
validFactorClasses()
Value
of valid factor vertex classes and the valid factor
vertex classes (used to create the factor vertices).
Details
The argument factorClasses to DynamicGraph,
and to returnFactorVerticesAndEdges and newFactor
is by default the returned value of this function.
If new factor vertex classes are created then factorClasses
should be set to a value with this returned value extended appropriate.
