I tried to use the SCAN.UPC package method UPCfast to generates an eset for the geo dataset: GSE21610.
eset <- UPCfast("GSE21610")
When I opened the eset I got this result:
ExpressionSet (storageMode: lockedEnvironment) assayData: 54675 features, 68 samples element names: exprs protocolData: none phenoData: none featureData: none experimentData: use 'experimentData(object)' Annotation:
There was no phenoData or featureData. Is this normal? I would like to access the phenoData of the eset.
