Hi all,
I am performing OPLS-DA analysis using the ropls package.
I would like to make a plot on the OPLS-DA variable importance, so VIP or loading factor (like this: https://www.researchgate.net/figure/OPLS-DA-scores-plot-and-variable-importance-plot-VIP-plot-for-discriminate-analysis-of_fig1_342444215).
I am working on metabolomics data, and can see that the research in this field most often use the software program SIMCA for it. However, I do not have that software, thus I would like to be able to make such plot.
Do any have any experience with performing OPLS-DA and seeing which metabolites add to the separation?
Thank you very much for any tip you might have!
