\title{An annotation data file that maps Entrez Gene identifiers to
  chromosome number}
\description{
  ratCHRLOCENTREZID2CHR maps Entrez Gene identifiers to the chromosome numbers the
  genes represented by the Locuslink identifiers reside
}
\details{
  This is an environment object containing key and value pairs. Keys are
  Entrez Gene identifiers and values are the corresponding chromosome numbers the
  genes reside. Values are vectors of length 1 or more depending on
  whether a give Entrez Gene identifier can be mapped to one or more chromosomes.

  Mappings were derived from data provided by:

  Golden Path:\url{http://gopher6/compbio/annotationSourceData/hgdownload.cse.ucsc.edu/goldenPath/currentGenomes//Rattus_norvegicus/database/}. Built: No build info available.
