I have a R program reading  data file of Illmina Human Whole Genome Bead Array.

BSData = readBeadSummaryData(dataFile = dataFile, ProbeID="PROBE_ID", skip=0)

This line works fine in R 2.11.1, but not in R 2.12.0.  It gives me something like

Error in readBeadSummaryData(dataFile = dataFile, ProbeID = "PROBE_ID",  :
  object 'QC' not found
A bug in new beadarray package maybe? Any Comment?
