                    estrogenFilenames <- c("low10-1.cel","low10-2.cel","high10-1.cel","high10-2.cel"
                    ,       "low48-1.cel","low48-2.cel","high48-1.cel","high48-2.cel")
                    affybatch.estrogen <- ReadAffy(
                            filenames=estrogenFilenames
                    ,       celfile.path=datadir
                    )
                    pData(affybatch.estrogen) <- data.frame(
                    "estrogen"=c("absent","absent","present","present"

                            ,       row.names=rownames(pData(affybatch.estrogen))
