     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between probe identifiers (key)
     and GenBank accession numbers (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 are
     vectors of length 1. NA is assigned to probe identifiers that can
     not be mapped to a GenBank accession number. Mappings between
     probe ids and GenBank accession numbers are assumed to be provided
     by users.

     Mappings were based on data provided by LocusLink

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

     built: Wed Jan 14 22:11:00 2004 Contains 250 randomly selected
     probes
