     This is an R environment object containing key and value pairs for
     the mappings between probe identifiers (key) and chromosomal
     location of genes (value). Keys can be accessed using ls(name) and
     values using get(key, name) or multiget(keys, name). Values are
     named vectors of signed integers of length 1 or more depending on
     whether a given probe id can be mapped to a single or multiple
     chromosomal locations. + and - signs are used to indicate the the
     strand of the chromosome. The names give the chromosome number of
     concern. NA is assigned to probe identifiers that can not be
     mapped to any chromosomal location data at this time. Mappings are
     obtained using data from LocusLink
     (www.ncbi.nlm.nih.gov/LocusLink) and Human Genome Project
     (http://genome.cse.ucsc.edu/goldenPath) based on unified mappings
     between probe identifiers and LocusLink ids and LocusLink ids and
     gene locations.
