For creating multi-coloumn responses on-the-fly, using cbind() like this works. However, you don't need that for the predictors; there you can get by with just using '+'. If you only have a few predictors/responses, this will work okay, but if you have many, it will take a lot of typing, and make the formula handling part of plsr() take _ages_. Then using matrices is easier and faster. -- Bjørn-Helge Mevik ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
