_D_e_s_c_r_i_p_t_i_o_n:

     This is an R environment (hash table) mapping GO ids to the
     specific textural description of the biological process, cellular
     component, or molecular function the genes represented by the GO
     ids are involved

_D_e_t_a_i_l_s:

     GO ids are keys and the corresponding GO textural descriptions are
     values. Values are name vectors of length 1. Names of the vectors
     indicating the GO category a term belongs to (MF = mocular
     function, BP = biological process, and CC = cellular component).

     All the obsolete GO textural descriptions are under the nodes
     "obsolete molecular function" (GO:0008369), "obsolete cellular
     component" (GO id GO:0008370), and "obsolete biological process"
     (GO:0008371). Each of these GO ids has a group of GO ids as their
     direct children (nodes directly linked to but below the GO ids
     along the directed acyclic graph defined by GO) with GO terms that
     were defined by GO but are deprecated in the current build. These
     deprecated GO terms were appended by "(obsolete)" when the data
     package was built.  

     Mappings were based on data provided by:
