Hi, I would like to be able to perform graph manipulations in R using packages from Bioconductor on a known metabolic gene network. I know it's possible to read and parse XML files from various websites, such as KEGG, into R. However, I'm having trouble locating the appropriate dataset(s) to download. I'm interested specifically in the metabolic insulin pathway in mice. Can anyone point me in the right direction for data from this pathway that can be parsed and manipulated as a graph in R? Thank you, Tim Clough
