Hi, I am working with plain hgu133a2 chips and I got an error in QCReport: plot(qc(abatch)) Error in get("spikes", envir = .qcEnv) : object ".qcEnv" not found I tried the approach suggested by James McDonald to Sanchita but, still it doesn't found the qcEnv, see below library(simpleaffy) > df1 <- get("alpha", .qcEnv) Error in get("alpha", .qcEnv) : object ".qcEnv" not found any help will be appreciated, Mayte ps. I am working with the last R+BioC version in MAC Intel desktop.
