hu6800PATH2PROBE mappes KEGG pathway ids to probe ids
This is an environment object with key and value pairs. Keys are KEGG pathway ids and values are the corresponding probe ids representing genes that are involved in the the pathways defined by the ids. Values are vectors of length 1 or greater depending on whether a given pathway id can be mapped to only one or more probe ids. Pathway ids can not be mapped to a probe identifier are assigned a value NA.
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:
