Title: CoCo in R

Abstract: The software CoCo to fit graphical models has been around for
some time. Some of the features of CoCo are efficient algorithms for large
contingency tables, exact tests, the EM algorithm, and procedures
for model selection.The program has been extended to also handle
continuous variables, by Gaussian graphical models and CG distributions.
CoCo can now be used from R under Windows as well as Linux.
Lately a tool for interacting with the graphs of the models
has been implemented in R. This tool, dynamicGraph, can also be used for
other packages.
