I have been trying to find DMRs from minfi normalized data using probe lasso() function of ChAMP package, but every time I am facing problem.
pdata <- pData(rgSetEx) mSetS <- preprocessSWAN(rgSetEx) betaS <- getBeta(mSetS) lasso <- champ.lasso(beta.norm = betaS, pd = pdata) "There is an error in this dataset"
Can someone please suggest if there is a way by which I can run lasso() on minfi data.
