Dear Bioconductor Users, I am not clear on the meaning of the table that is output from the AffyRNAdeg and how to use it to find bad slides. I am also not clear on how to use the hist command to see if the data is as it should be. I would appreciate any pointers or literature references. Thanks and best wishes, Rich ------------------------------------------------------------ Richard A.
