Hi @bioinformatics_noob,
(this post has been moved to a new post topic)
Sorry that this is unrelated to your question, but how did you format your methylation dataset before inputting it into mixOmics? Were your columns just the coordinates of CpG sites and the elements of the array the C/T frequency at those sites for each sample?
You can have a look a the supplemental of the DIABLO paper that describes the type of methylation data we accessed to in two studies.
