I've loaded data into a LumiBatch object, x.lumiR, that includes control probe information.

If I use getControlData(x.lumiR), I get data frame returned with the expression values for the control probes.

What I want, however, is to get the information about the beadNum, detection, and se.exprs for the control probes.

If I use getControlData(x.lumiR, type = 'LumiBatch'), I expected to get a lumiBatch object back with this information. Instead I just get the original x.lumiR object back. 

How can I get the same information (beadNum, detection, exprs, se.exprs) for the control probes as I can for the experimental probes?

Thanks
