     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between probe identifiers (key)
     and gene names (value), which are  descriptions used for gene
     reports. 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.
     Mappings between peobe ids and gene names were obtained through
     their mappings to LocusLink ids. NA is assigned to probe
     identifiers that can not be mapped to any gene name at this time.

     Mappings were based on data provided by LocusLink

     Source data built: LocusLink built: January 13, 2004.<URL:
     ftp://ftp.ncbi.nih.gov/refseq/LocusLink/LL_tmpl.gz>. Package
     built: Wed Jan 14 22:11:04 2004 Contains 250 randomly selected
     probes
