hgu133aPMID2PROBE mappes PubMed identifiers to probe identifiers representing genes cited by the publications identified by the PubMed identifiers
This is an environment object with key and value pairs. Keys are pubMed ids and values are the corresponding probe ids. Values are vectors of length 1 or greater depending on whether a given PubMed id can be mapped to only one or more probe ids. PubMed ids can not be mapped to any probe identifier are assigned a value NA.
Mappings were based on data provided by:
