Dear Li, to clarify: you can get the source of the package from the Bioconductor svn: See http://wiki.fhcrc.org/bioc/DeveloperPage and https://hedgehog.fhcrc.org/bioconductor/trunk/madman/Rpacks If this means nothing to you, then please don't worry, and you could use the package once it is added to the list of packages for the build system, and then you will find it here: http://www.bioconductor.org/packages/2.3/bioc/ If you are comfortable with svn and installing packages from source, we would be interested in your feedback.
