mismatch of slot name in as.data.table(prediction) intentional?

[mb706]

as.data.table(prediction) has column row_id, but the slot in the Prediction / PredictionData object is row_ids, is that intentional? What is the naming rule here?

Very slightly off topic but I get very confused when to use rows and when to use row_ids. Picking one of the three and being consistent would make things much easier

The refactoring went wrong here. I agree that we should stick to row or row_id, but I'm unsure what would be a good rule for singular and plural.
