_D_e_s_c_r_i_p_t_i_o_n:

     org.Sc.sgdGENENAME is an R object that maps ORF identifiers to the
     corresponding gene name.

_D_e_t_a_i_l_s:

     Each ORF identifier maps to a named vector containing the gene
     name. The vector name corresponds to the ORF identifier. If the 
     gene name is unknown, the vector will contain an 'NA'.

     Gene names currently include both the official (validated by a
     nomenclature committee) and preferred names (interim selected for
     display) for genes. Efforts are being made to differentiate the
     two by adding a name to the vector.

     Mappings were based on data provided by: Yeast Genome (
     ftp://genome-ftp.stanford.edu/pub/yeast/data_download ) on
     2008-Sep06
