Hey all,
I’m running a nested MFold cross-validation for rCCA and noticed that tune.rcc() does not have a scale argument. If I’m understanding correctly, rcc() already handles centering internally but doesn’t scale within each training fold during tuning.
Other mixOmics functions (e.g., PLS/PCA-family methods) already have existing scaling options.
Is there a reason tune.rcc() does not currently support scaling, and could you add this functionality?
Thank you
