Hi there, thank you for the great package!
I am having some trouble with obtaining the Q2 values after running perf() for pls regression. Since a few weeks the call for tune.spls$Q2.total, using your case study data as example, returns NULL. I thought that tune.spls$measures$Q2.total would give me the same values, however they seem to be considerably different from what I used to get except for the first PC. Am I missing something here? I am very grateful for any help!
Sorry that I am not including a reproducible example but I am also having some issue with reprex/pandoc. Here is what I get calling tune.spls$measures$Q2.total with your case study data for spls:
$summary
