     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between probe identifiers (key)
     and UniGene cluster ids (value). Keys can be accessed using
     ls(name of the environment) and values using get(key, name of the
     environment) or mget(keys, name of the environment) . Values may
     be vectors of length 1 or greater depending on whether a given
     probe identifier can be mapped to only one or more UniGene cluster
     ids. Mappings between probe ids and UniGene ids were obtained
     through their mappings to LocusLink ids. NA is assigned to probe
     identifiers that can not be mapped to any UniGene cluster id at
     this time.

     Mappings were based on data provided by LocusLink

     Source data built: LocusLink built: January 13, 2004.<URL:

     built: Wed Jan 14 22:11:09 2004 Contains 250 randomly selected
     probes
