zzz-gModel: Old: Class "gModel" - graphical models
Description
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 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.
