Maybe we should put the percentage of explained variance on the plotIndiv graph when the object is a PCA?

    Too brief? Apologies, I need to restrain my typing due to a computer elbow injury.

    In presence of missing data (for the input data), i can only retrieve the eigenvalues on the components selected by the user. In other words, I do not know the total variance of the data and thus cannot get the explained variance per component.

    Yes, agreed, This explains why we have different outputs when you run a PCA-missing values (via nipals) and a normal PCA. For missing values, proceed as usual.
