I'm attempting my first microarray analysis on a methylation dataset
(Illumina Infinium) comprising identical twins (24 -> 12 per array). I
thought I'd try the methylumi package - I can import the data, but when
I try to Normalise between the two arrays I get an error:
Error in function (classes, fdef, mtable) :
unable to find an inherited method for function "QCdata<-", for
signature "MethyLumiSet", "NULL"
According to the vignette, QCdata is not required.
I know some basics but am not an expert in R.
Any help would be appreciated.
