[BioC] offline gene name conversion

[Rainer Tischler]

Dear all,

I have been using the bioMart and DAVIDQuery R-packages to convert gene identifiers into different formats. Unfortunately, both of these packages require direct internet access for every conversion.
Is anybody aware of an R-package or script which supports "offline" gene name conversion, i.e. based on previously downloaded gene name database files (disk space is no problem)?

Many thanks,
Rainer
