     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between probe identifiers (key)
     and the RefSeq accession for a mRNA record (value). Keys can be
     accessed using ls(name of the environment) and values using
     get(key, name of the environment) or multiget(keys, name of the
     environment). Values may be vectors of length 1 or greater
     depending on whether a given probe id can be mapped to only one or
     more RefSeq accession for a mRNA record. NA is used for probe ids
     that can not be mapped to a RefSeq accession for a mRNA record at
     this time.
