The gRbase Package for Graphical Modelling in R

We have developed a package, called , consisting of a number of classes and associated methods to support the analysis of data using graphical models. It is developed for the open source language, R, and is available for several platforms. The package is intended to be widely extendible and flexible so that package developers may implement further types of graphical models using the available methods. contains methods for representing data, specification of models using a formal language, and is linked to , an interactive graphical user interface for manipulating graphs. We show how these building blocks can be combined and integrated with inference engines in the special cases of hierarchical log-linear models (undirected models). gRbase gRbase dynamicGraph
