hu6800LOCUSID {hu6800} | R Documentation |
hu6800LOCUSID mappes probe ids to LocusLink ids corresponding to genes represented by the probe ids.
This an environment object with key and value pairs. Keya are probe ids and values are the corresponding are LocusLink ids. Values are vectors of length 1. NA is assigned to probe ids that can not be mapped to a LocusLink id at this time.
Mappings were based on data provided by:
