Hi all,

I am trying to follow the pipeline using minfi, limma, miss methyl etc. using "A cross-package Bioconductor workflow for analysing methylation array data [version 3; peer review: 4 approved]" - Jovana Maksimovic et al" and I am stuck on page 32 of the vignette (differential variability) because age.rgSet cannot be extracted no matter what I try. It does extract age.targets but there is definitely an issue with rgset. I tried redownloading the rdata object and yet it won't work. Since I don't have idat files, I don't know what else to do fix this error. Thanks!

Code should be placed in three backticks as shown below

load(paste(newdir,"ageData.RData",sep="/")) 

# include your problematic code here with any corresponding output 

# please also include the results of running the following in an R session 

Error in h(simpleError(msg, call)) : 
  error in evaluating the argument 'x' in selecting a method for function 'nrow': no slot of name "elementMetadata" for this object of class "RGChannelSet"
