Are the extraColumnSlots of a class that extends GenomicRanges limited to DataFrame objects?
Background: I wrote a class that extends the GRanges class. It has a matrix as the extraColumnSlots. When I use replaceROWS,GenomicRanges,GenomicRanges-method (via inheritance) it extracts this extraColumnSlots as a DataFrame object by use of GenomicRanges:::extraColumnSlotsAsDF. This means that the subsequent call to update() in replaceROWS,GenomicRanges,GenomicRanges-method fails because the class definition expects a matrix for the extraSlotNames but gets a DataFrame. In this case, it's not a problem for me to change my extraColumnSlots element to a DataFrame in the class definition. However, more generally, some guidance on what classes are and are not allowed in extraColumnSlots would be appreciated.
