I want to compute P/A calls at gene-level probesets so that it can be utilized for removing unexpressed probe after rma (target = core). As far as I'm concerned, oligo::paCalls can not handle this. There seems a package "xps" can fix that, which unfortunately could not be installed at Windows 64-bit. Is there some other methods could filter the unexpressed probes? Any advice would be appreciated!
eset <- oligo::rma(object = affyRaw, target = 'core') xpa <- oligo::paCalls(object = affyRaw, method = 'PSDABG') xpa <- oligo::paCalls(object = affyRaw, method = 'DABG')
