plot( factor( <GROUPINGVAR> ) , <PLOTVARS> )

I could perform the PLSDA in R. however I would also like to perform a leave-one-out cross validation in order to assess the performance of my model. My supervisor told me that I should focus on the R2/Q2 ratios.
However when I read the instruction for running the
