sPLS choice of optimal number of components

Hello,

I have been mixOmics and I am really impressed with the analysis I can do. I am using sPLS and I have a question. I run perf first to select the optimal number of components using PLS. Then I run sPLS using the ncomp calculate from perf function and I also tuned the optimal number of keepX variables. After I run tune.spls I got outputs tune.spls.MAE $choice.keepX for optimal number of keepX
ncompspls<-tune.spls.MAE$choice.ncomp$ncomp
When I build the final sPLS model shall I use ncompspls or the ncomp from perf function?

Many thanks,
Maria

dear @MARIAGLY,
Great to have you using our package! I would use as the number of final components the components indicated in ncompspls as this is your final sparse model (the number of component from the PLS tuning is a first indication only).
Note that we will be adding adding more functionalities on the tune function for s/PLS in the coming month with @aljabadi.
