_D_e_s_c_r_i_p_t_i_o_n:

     drosophila2UNIGENE is an R environment that provides mappings
     between manufacturer ids and UniGene ids.

_D_e_t_a_i_l_s:

     Each manufacturer id is mapped to a UniGene id. An 'NA' is
     reported if the manufacturer id cannot be mapped to UniGene at
     this time. 

     A UniGene id represents a cluster of sequences of a gene. Using
     UniGene ids one can query the UniGene database for information
     about the sequences or the LocusLink database for information
     about the genes.  

     Mappings were based on data provided by:
