ZOLD-gModel: Old: Class "gModel" - graphical models

Description Usage Arguments Value Author(s) See Also Examples

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.
