_D_e_s_c_r_i_p_t_i_o_n:

     This package stores annotation data for genes from other organisms
     that have homologous relationships with genes in Bos taurus.
     Homologous genes are genes that share an arbitrary threshold level
     of similarity determined by alignment of matching bases

_D_e_t_a_i_l_s:

     Data stored in this package are for genes that have homology with
     Bos taurus. Homologous genes of other organisms are stored in
     separate packages with names in the format of three-letter
     organism code plus homology. The three-letter organism code
     consists the first letter of the genus name and the first two
     letters of the species name (e. g. hsa for Homo sapiens). 

     Help files for individual data environments contain detailed
     information about the data and the usage.

     The package was built using a downloadable R package - AnnBuilder
     (download and build your own) from www.bioconductor.org using the
     following public data sources:   

     HomoloGene:<URL: 
     ftp://ftp.ncbi.nih.gov/pub/HomoloGene/old/hmlg.ftp>. Built:
     HomoloGene built date not available 

     The function btahomology() provides information about the data
