Let say I've created a directed graph of pathway which consist of connected compounds/reactions as the nodes (using Rgraphviz), how can I show the enzyme involved in the transition between the compounds? Can someone help me by providing source code example to retrieve the enzyme information from KEGG for particular compounds or reactions? and also how to incorporate such information into Rgraphviz. Thanks alot..
You haven't updated anything regarding your problem. Just by changing the title doesn't interest anyone unless and untill you will post something what you have done. If you had tried then people want to see what's your problem (R code) and how it can be solved.
Can you give a try with: SubpathwayMiner - A software package for annotation and identification of the KEGG pathways
