Hi all, I looked around on the BioC site for information on any implementations of Bayesian networks in Bioconductor. I couldn't find anything. From the literature it looks like Bayesian networks for gene expression has been around for almost as long as microarrays, yet no implementations exist in R/Bioconductor - which seemed a little odd to me. Is there a reason for this? Are Bayesian networks somehow dubious, or is it just that nobody has written a package? Would love to hear from the experts... Thanks, Jake

Another word for Bayesian networks is graphical models. On Bioconductor, "GraphsAndNetworks" on http://www.bioconductor.org/packages/release/Software.html is probably a good start. I believe geneTS is one such package. On CRAN, a great page for this is http://cran.r-project.org/src/contrib/Views/gR.html.

hi Jacob, Sorry, I am not an expert and in fact just a newbie in statistical genetics and R. There is a package called "deal" in CRAN for Bayesian Network Learning. Never used it before though.
