ZOLD-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.

Usage

gModel(formula, gmData)

Arguments

`formula`	an object of class `formula`.
`gmData`	an object of class `gmData`.

Value

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.
