Multiblock data integration

I have LCMS data and NMR data and i want to perform multiblock data integration, what method i should use between rCCA and (s)PLS. also in sPLS guide here Multiblock (s)PLS | mixOmics how can i use only LCMS nd NMR data and not like in the example (where there is mirna data mrna data and protein data)

If you have any other suggestion feel free to let me know please
Thank you

hi @Anouar

rCCA only focuses on integrating the data sets, whereas sPLS also adds variable selection. You will have to look into our examples on our website to work out the difference, and how to input those data in the package.
