It means that you have set the printer layout information in RG$printer to missing values. If you do that you have to expect to get an NA error somewhere downstream.

Dear BioC Are rma/gcrma/mas5.0/ etc limited by a minimum number of chip (.cel) files? I am calling expression values on a dataset with only 2 chips (treated/control, pooled RNA from n=5). Is 2 chips too few .cel files for these methods? Thanks for your help Aedin
