[BioC] methylumi: cannot normalizeMethyLumiSet

[Jinyan Huang]

I donot have QCdata.

> library(methylumi)
> des<-read.table("des.txt",header=T,sep="\t")
> mldat <- methylumiR("data.txt",sampleDescriptions = des)
> avgPval <- colMeans(pvals(mldat))
> toKeep <- (avgPval < 0.05) & (des$grade!="Missing/No tumor")
> mldat.norm <- normalizeMethyLumiSet(mldat[,toKeep])

Error in function (classes, fdef, mtable)  :
  unable to find an inherited method for function "QCdata<-", for
signature "MethyLumiSet", "NULL"
