The gRbase package is developed for the open source language, R, and is available for several platforms.

Undirected graphs, relevance, and independence defined as set separation. Clique trees as undirected graphs on variable sets, and a normalised form for them called Almond trees which are a tree-structured generalization of binary independence.

## Graphical Models with R

Graphical models in their modern form have been around since the late s and appear today in many areas of the sciences. Along with the ongoing developments of graphical models, a number of different graphical modeling software programs have been written over the years.

In recent years many of these software developments have taken place within the R community, either in the form of new packages or by providing an R interface to existing software. This book attempts to give the reader a gentle introduction to graphical modeling using R and the main features of some of these packages.

Topics covered in the seven chapters include graphical models for contingency tables, Gaussian and mixed graphical models, Bayesian networks and modeling high dimensional data. The book, written by some of the people who laid the foundations of work in this area, would be ideal for researchers who had read up on the theory of graphical models and who wanted to apply them in practice. It would also make excellent supplementary material to accompany a course text on graphical modelling.

The lecture itself will sometimes digress to web-based material and Java applets for demonstrations.
