Have you tried using the annotation package yet?


Here is another link to give you some directions about how to use
annotation packages in case you are new to this:


But if you have already tried these things, can you please tell me what
you have tried so far ( with results to a sessionInfo() in R) ? We even
have a posting guide to help you know what sorts of things to put into
your post here:


Maybe if I know a little bit more about what you are trying to do I can
help you out better. ;)
