_D_e_s_c_r_i_p_t_i_o_n:

     hgu133plus2ALIAS is an R object that provides mappings between
     common gene symbol identifiers and manufacturer identifiers.

_D_e_t_a_i_l_s:

     Each gene symbol is mapped to a named vector of manufacturer
     identifiers. The name represents the gene symbol and the vector
     contains all manufacturer identifiers that are found for that
     symbol. An 'NA' is reported for any gene symbol that  cannot be
     mapped to any manufacturer identifiers.

     This mapping includes ALL gene symbols including those which are
     already listed  in the SYMBOL map.  The SYMBOL map is meant to
     only list official gene symbols,  while the ALIAS maps are meant
     to store all used symbols.

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