\begin{Description}\relax
R environments that provides mappings between public database identifiers and internal
HomoloGeneIDs (HGID) used by NCBI to represent sequences for
Homo sapiens. Public database identifiers include Entrez Gene identifiers (LL) and GenBank
Accesion/RefSeq numbers (ACC).
\end{Description}
\begin{Details}\relax
Each R environment provides mapping between either HomoloGeneIds and
database identifiers. or the converse. The mapping direction is indicated by
the name of the environment. For instance, hsahomologyACC2HGID provides
mappings between GenBank accession numbers and HomoloGeneIds.

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

Mappings contained were based on data provided by HomoloGene.
