Can you post dput(head(eqn, 30)) so we can take a look at your data? It's something of a cryptic error and that would go a long way in helping us help you.
Without that though, I'm not sure you need the I(as.matrix.(dep)) and I(as.matrix(ind)), I would imagine (untested) that eqn <- data.frame(depy = dep, indx = ind) would work (probably better as I() changes things just a little). I have a hunch that the colnames of eqn are not actually depy and indx and that's what ultimately leads to the error. Can you look at colnames(eqn) and use those exactly in the formula to plsr? That might fix it. Michael On Sat, Mar 3, 2012 at 5:01 PM, westland <westl...@uic.edu> wrote: > I am still/again having trouble getting PLSR to recognize the input data > frames.
