\begin{Description}\relax
R environments that provides mappings between public database ids and internal
HomoloGeneIDs (HGID) used by NCBI to represent sequences for
Xenopus laevis. Public database ids include LocusLink ids (LL) and GenBank
Accesion/RefSeq numbers (ACC).
\end{Description}
\begin{Details}\relax
Each R environment provides mapping between either HomoloGeneIds and
database ids, or the converse. The mapping direction is indicated by
the name of the environment. For instance, xlahomologyACC2HGID provides
mappings between GenBank accession numbers and HomoloGeneIds.

For each environment, a given id will map to a named vector of ids,
the names of which are the NCBI code for that organism.

Mappings contained were based on data provided by HomoloGene.
