Among the good strengths of R is the fact that it may be supplemented with more packages which are bundled as offers using the offer supervisor. (e.g., sem or OpenMX do structural equation modeling) or that could be additional utilizing the supply command. Most packages are right obtainable through the CRAN repository. Others are available for the BioConductor repository.
