Hi I used pls.pcr on a dataset x[!sub,]. How can I get the scores for another dataset, say x[sub,]? I couldn't reproduce the scores for the training set by multiplying the data with the loadings, even after first scaling the data (scale()). pls.pcr only gives the XScores for the training data. many thanks for a hint cheers christoph -- Christoph Lehmann <christoph.lehmann at gmx.ch>
