     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between  probe identifiers (key)
     and LocusLink ids (values). 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 LocusLink ids. NA is
     assigned to probe identifiers that can not be mapped to a
     LocusLink id at this time.

     Mappings were based on data provided by LocusLink
