I wouldn't necessarily classify this as a bug. More as a difference of
opinion between implementers. However, it has been possible since early
January to duplicate the results of expresso via the command rma() using
the parameter bgversion=2 (with slight rounding differences). Or
alternatively via expresso you can use bg.method="rma2" and this will
duplicate the background used in rma() (exactly).

He found that the results from this rma streamline version differed from the results obtained using the individual commands: eset<. expresso(), normalize.method=quantiles, bg.method="rma", pmcorrect.method= "rma" etc. etc.
