[galaxy-dev] edgeR Tool Shed

Hello, I have some questions about the edgeR (fcaramia) and digital_dge (fubar) repositories in tool shed. What is the difference between the two respositories in terms of being able to run edgeR? What is the proper way to install R so that the tool wrappers can use edgeR? What versions of R and edgeR do each of the repositories work with? Similaraly why is it that the repositories do not have information about which versions of R and edgeR are compatible? I have tried both repositories and have installed R and loaded the edgeR library but the tools do not seem to work. There are no errors coming up but the outputs are empty. The input file works with edgeR ran the traditional way through R (without Galaxy). Thank you, Richard
