The predicted values and the residuals are shown for robust PLS using the optimal number of components.

Robust PLS based on partial robust M-regression is available at `prm`

.
Here the function `prm_cv`

has to be used first, applying cross-validation
with robust PLS. Then the result is taken by this routine and two plots are generated
for the optimal number of PLS components: The measured versus the predicted y, and
the predicted y versus the residuals.

A plot is generated.
