[BioC] loading/accessing older GO.db and org.Hs.eg.db data

[Jonathan Mortensen [guest]]

Hello,

I am interested in accessing old versions of GO.db and org.Hs.eg.db data. I would like to them to potentially be different versions, so entirely downgrading bioconductor and/or R (the standard response) does not seem to make sense. Also, I recognize that identifiers and mappings may be missing or not match -- That is ok.

After reading through the AnnotationDbi documentation, it seems to me that annotation packages come from SQLite databases. If so, is it possible to create new annotation objects using older SQLite databases? Are there archived SQLite databases of these data?

If not, what is a reasonable method in bioconductor to get older versions of the data?

There are a few posts here that seem to indicate that different versioning is not a good idea. But, any direction would be much appreciated!

Thanks,
Jonathan Mortensen
