     This is an R environment (hash table like) object containing key
     and value pairs for the mappings between probe identifiers (key)
     and gene symbols (value), which are symbols used to report genes.
     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
     probe ids and gene symbols were obtained through their mappings to
     LocusLink ids. NA is assigned to probe identifiers that can not be
     mapped to any gene symbol 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 22:11:08 2004 Contains 250 randomly selected
     probes
