     Hs6UG171ENSEMBL is an R object that contains mappings between 
     Entrez Gene identifiers and Ensembl gene accession numbers.

_D_e_t_a_i_l_s:

     This object is a simple mapping of Entrez Gene identifiers <URL:
     http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene> to Ensembl
     gene Accession Numbers.

     Mappings were based on data provided by BOTH of these sources:
     <URL: http://www.ensembl.org/biomart/martview/> <URL:
     ftp://ftp.ncbi.nlm.nih.gov/gene/DATA>

     This mapping is a combination of NCBI to ensembl IDs from BOTH
     NCBI and ensembl.  Users who wish to only use mappings from NCBI
     are encouraged to see the ncbi2ensembl table in the appropriate
     organism package.  Users who wish to only use mappings from
     ensembl are encouraged to see the ensembl2ncbi table which is also
     found in the appropriate organism packages.  These mappings are
     based upon the ensembl table which is contains data from BOTH of
     these sources in an effort to maximize the chances that you will
     find a match.
