     org.Sc.sgdPMID is an R object that provides mappings between ORF
     identifiers and PubMed identifiers.

_D_e_t_a_i_l_s:

     Each ORF identifier is mapped to a named vector of PubMed
     identifiers. The name associated with each vector corresponds to
     the ORF identifier.  The length of the vector may be one or
     greater, depending on how many PubMed identifiers a given ORF
     identifier is mapped to. An 'NA' is reported for any ORF
     identifier that cannot be mapped to a PubMed identifier.

     Titles, abstracts, and possibly full texts of articles can be
     obtained from PubMed by providing a valid PubMed identifier. The
     pubmed function of annotate can also be used for the same purpose.

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