Hello. I have been trying to use the lumi package to analyze illumina array data. However, I have two sets of data that were obtained with different chip versions and that have different number of probeIDs/ rows. Can I combine the two datasets (excluding the nuID's that are not present in both)? Thank you. Luis.

Hi Luis, Yes, you can merge them by excluding the non-overlapping probes. That is the benefit of using nuIDs because the same nuID can make sure the probes are the same even though they are from different types of chips.
