Hi, I have managed to format my data into a single datframe consisting of two AsIs response and predictor dataframes in order to supply the plsr command of the pls package for principal components analysis. When I execute the command, however, I get this error: > fiber1 <- plsr(respmat ~ predmat, ncomp=1, data=inputmat,validation="LOO") Error in model.frame.default(formula = respmat ~ predmat, data = inputmat) : invalid type (list) for variable ''respmat'' I happen to have a lot of NAs in some of the columns. Is that the problem?...
