## Mappings between public database ids and NCBI's Internal HomoloGeneIDs for Rattus norvegicus

### Description

R environments that provides mappings between public database ids and internal HomoloGeneIDs (HGID) used by NCBI to represent sequences for Rattus norvegicus. Public database ids include LocusLink ids (LL) and GenBank Accesion/RefSeq numbers (ACC).

### Details

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, rnohomologyACC2HGID 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.

### Examples

        require("annotate") || stop("annotate unavailable")
        xx <- as.list(rnohomologyLL2HGID)
            if(length(xx) > 5){
                    # Get the value of the first key
                    xx[2]
                    # Get the value for a few keys
                    if(length(xx) >= 3){
                            xx[2:4]
                    }
            }
