annaffyPATH {annaffy} | R Documentation |
This is an R environment (hash table like) object containing key and value pairs for the mappings between probe identifiers (key) and pathway identifiers defined by KEGG (value). Keys can be accessed using ls(name of the environment) and values using get(key, name of the environment) or multiget(keys, name of the environment). Values may be vectors of length 1 or greater depending on whether a given probe identifier can be associated with only one or more pathways. Mappings between probe ids and pathway ids were obtained their mappings to LocusLink ids. NA is assigned to probe identifiers that can not be associated with any pathway at this time. Mappings between pathway ids to pathway names can be found in a separate data package named KEGG.
Mappings were based on data provided by KEGG
