_D_e_s_c_r_i_p_t_i_o_n:

     ratLLMappingsGO2LL maps Gene Ontology (GO) identifiers to Entrez
     Gene identifiers for genes whose products have the functions
     corresponding to the GO identifiers

_D_e_t_a_i_l_s:

     This is an environment object containing key and value pairs. Keys
     are GO identifiers and values are Entrez Gene identifiers. Values
     are vectors of length 1 or more depending on whether a GO
     identifier can be mapped to one or more Entrez Gene identifiers.
     Names of values are evidence code that indicate the type of
     evidences that support associations between genes and GO
     functions. 

     The evidence codes in use include:

     IMP: inferred from mutant phenotype   IGI: inferred from genetic
     interaction IPI: inferred from physical interaction   ISS:
     inferred from sequence similarity  IDA: inferred from direct assay
       IEP: inferred from expression pattern   IEA: inferred from
     electronic annotation   TAS: traceable author statement   NAS:
     non-traceable author statement   ND: no biological data available 
      IC: inferred by curator

     Mappings were derived from data provided by:

     Entrez Gene: Not available
