I thought that all of the information about each chipset (i.e. platform) was in the corresponding R package.

For example, hgu219.db is the annotation package for the hgu219 platform.

However, my key lookup results differ depending on the package version of AnnotationDbi, even when the hgu219.db package versions are the same.

So for example,

keys(hgu219.db, keytype = 'UNIPROT')

gives a different list of UNIPROTs depending on the AnnotationDbi version.

I thought all of the info was in the hgu219.db package. My thinking must be incorrect?

Can someone explain why this is happening?
