Dear Kasper,
For older objects I have been trying to update the annotation to
IlluminaHumanMethylation450kanno.ilmn12.hg19_0.2.1
But I am getting an error:
RGset.c <- updateObject(RGset.7)
"Error in if (object at annotation["annotation"] == "ilmn.v1.2")
object at annotation["annotation"] <- .default.450k.annotation :
missing value where TRUE/FALSE needed"
The RGset is a plain one:
RGset.7
"RGChannelSet (storageMode: lockedEnvironment)
assayData: 622399 features, 605 samples
element names: Green, Red
phenoData
sampleNames: 7310440029_R05C01 7310440029_R05C02 ...
7497398051_R02C01 (605 total)
varLabels: hofnum labnr ... v050 (41 total)
varMetadata: labelDescription
Annotation
*array: IlluminaHumanMethylation450k"*
(Running on R 3.0.2 with minfi 1.8.8).
Do you have any idea on how to update?
Best wishes
