hgu95av2PATH mappes probe ids to ids of KEGG pathways in which the genes represented by the probe ids are involved
This is an environment object with key and value pairs. Keys are probe ids and values are the corresponding KEGG pathway ids. Values are vectors of length 1 or greater depending on whether a given probe identifier can be associated with only one or more pathways. NA is assigned to probe ids that can not be associated with any pathway at this time.
Pathway name for a given pathway id can be obtained using the KEGG data package that can either be built using AnnBuilder or downloaded from Bioconductor http://www.bioconductor.org.
Mappings were based on data provided by:
