[BioC] gcrma commands in expresso function

[Anthony Bosco]

HI,

I want to use gcrma background correction in expresso function (so I 
can use other normalisation methods and different summary methods).

However I seem to get errors, can someone please check my R codes below:

Also, I don't know where to find/search the archives of other FAQ for 
bioconductor

Regards


Anthony



cs.data<-ReadAffy()

gcrma.mle<-bg.correct.gcrma(cs.data,gcgroup=getGroupInfo(cs.data),estimate="mle")

gcrma.eb<-bg.correct.gcrma(cs.data,gcgroup=getGroupInfo(cs.data),estimate="eb")

eset<-expresso(gcrma.eb,bg.correct=FALSE, 
normalize.method="loess",pmcorrect.method="pmonly",summary.method="medianpolish")
