     hgu133plus2ACCNUM is an R object that contains mappings between a
     manufacturer's identifiers and GenBank accession numbers.

_D_e_t_a_i_l_s:

     This object was produced by first mapping the manufacturer's
     identifiers to Entrez Gene identifiers <URL:
     http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=gene>. The mapped
     Entrez Gene identifiers then serve as the point of linkage to the
     GenBank accession numbers.

     Each manufacturer identifier maps to a vector containing a GenBank
     accession number.

     Mappings were based on data provided by: Entrez Gene (
     ftp://ftp.ncbi.nlm.nih.gov/gene/DATA ) on 2007-Aug23
