Hi Haowen, I know this reply is a bit late, but since you have so few samples (2 vs. 2), I recommend trying "ruv4" instead of the default "ruvinv" for RUVfit. I suggest you also use k=1. See the example in the vignette in section 7.2: https://bioconductor.org/packages/release/bioc/vignettes/missMethyl/inst/doc/missMethyl.html#removing-unwanted-variation-when-testing-for-differential-methylation
Thank you very much.

Hi, Oshlack, Thanks for developing this wonderful tool for methylation array GO analysis. I have encountered some issues when using the package for analysis of 4 samples (two control, two treatments). Could you please give me some suggestions on how could I work out the code? Thanks a lot!
Here is the code:
########### if I added randomization=TRUE to the RUVfit, it worked. But I still could not get rfit2 work.
Could you please let me know how should i modify the code? ############## I am a fresh man in bioinformatic analysis, any help is appreciated.
Best, Haowen
