when I load m-values for a differential methylation experiment in ChAMP I get the following error message with champ.norm, for both BMIQ and PBC. any suggestions welcome for how to solve?
Error in 1:ncol(beta) : argument of length 0
In addition: Warning messages:
1: In dir.create(resultsDir) : '.\CHAMP_Normalization' already exists
2: In min(beta, na.rm = TRUE) :
