| gModel {gRbase} | R Documentation |
The general class gModel contains a formula object and a
gmData object. Implementations of different
specific graphical model classes can inherit from this class and
provide methods for parsing the formula. This is illustrated in the
implementation of a class for hierarchical log–linear models,
hllm.
gModel(formula, gmData)
formula |
an object of class formula. |
gmData |
an object of class gmData. |
gModel creates an object of class gModel with the two
components formula and gmData. These components can be
retrieved or replaced using the accessor functions of the same
names. Also, a gModel object may be manipulated using the
dynamicGraph interface.
