     This data is taken from the 'estrogen' package. It was created to
     be used in the vignette for the 'puma' pacakge. It can be produced
     using the following code:


                     library(estrogen)
                     datadir <-
     file.path(.find.package("estrogen"),"extdata") 
                     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"
                             ,"absent","absent","present","present")
                             ,      
     "time.h"=c("10","10","10","10","48","48","48","48")
                             ,      
     row.names=rownames(pData(affybatch.estrogen))
                     )
