The data from the estrogen package as an AffyBatch object

Description

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))
                )

Usage

data(affybatch.estrogen)

Format

An AffyBatch object containing 8 HG_U95Av2 arrays, in a 2 x 2 factorial design, with 2 replicates for each combination of factors. The factors are estrogen (absent of present) and time.h (10 or 48).
