Kegggraph: A Graph Approach to Kegg Pathway in R and Bioconductor

We demonstrate the capabilities of the KEGGgraph package, an interface between KEGG pathways and graph model in R as well as a collection of tools for these graphs. Superior to preceding approaches, KEGGgraph maintains the pathway topology and allows further analysis or dissection of pathway graphs. It parses the regularly up-dated KGML (KEGG XML) files into graph models maintaining all essential pathway attributes.
