Hi Fabrice,
Suppose you are using Tims package.
library("IlluminaHumanMethylation450k.db")
That would give you access to this object:
IlluminaHumanMethylation450kGO
Which would allow you to get the GO IDs for all your probes etc.
So then I think your question is: how could you get the GO terms and
the
pathways?
Well how about doing this?
library(GO.db)
ids = c( "GO:0008150", "GO:0001869") ## just for example..
result = select(GO.db, keys =ids, cols=c("DEFINITION","TERM"))
That value in result could then be merged (using the merge method) to
your previous results (the ones that have the GOIDs)
