Hi, Pan,

We already have some in the LLMappings packages (e.g.
humanLLMappings). But they only provide GenBank accessions, go,
UniGene and PubMed mappings to Entrez Gene. We will provide three new
SQLite-based annotation packages in the next release (in a month), for
human, mouse and rat, respectively. Their structure will be similar to
affymetrix gene chip annotation packages such as hgu95av2, but the
index will be Entrez Gene ID instead of probeset ID. Stay tuned...

best
