[BioC] OntoCompare Error

[Johannes Graumann]

Hello,

With the help of this list I succeeded in creating an annotation package
using ABPkgBuilder/AnnBuilder ("Mus.musculus.GoMap.20070223"), which
installs fine.
I then tried to run goTools' ontoCompare function like this:

result <- ontoCompare(ProtNames, probeType = "Mus.musculus.GoMap.20070223")

After a LONG time, it stops with the following:
        Error in as.vector(x, mode) : invalid argument 'mode' error

Does anyone spot what I'm doing wrong?

Thanks, Joh
