Extract folds from cross-validation with perf

[nabo]

Hello,

I’m using the perf() function to assess feature stability in sPLS2 regression analysis, following the approach outlined here: 4 PLS on the liver toxicity study | mixOmics vignette.

I’m fairly new to R and mixOmics. Is there an easy way to view the individual folds in the cross-validation? I’d like to examine a specific fold to see which samples were used for training and testing, as well as which features were selected in the sPLS model for that fold. Thank you!

Hi @nabo,

Unfortunately I am not aware of an easy way to extract the individual folds in the cross-validation as performed by perf(), although this is something we may look at extracting over the coming months.

Cheers,
Eva
