\keyword{datasets}{xlahomology}
\begin{Description}\relax
This package stores annotation data for genes from other
organisms that have homologous relationships with genes in
Xenopus laevis. Homologous genes are genes that share an arbitrary
threshold level of similarity determined by alignment of matching bases
\end{Description}
\begin{Details}\relax
Data stored in this package are for genes that have homology with
Xenopus laevis. 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 xlahomology() provides information about the data files
