I am still/again having trouble getting PLSR to recognize the input data frames. Here is what I have done: I read in an 10000 x 8 table of data to 'pls'
assign the first four columns to matrix 'dep' and the second four to matrix 'ind' with the following commands: dep <- pls[,1:4] ind <- pls[,5:8] I create the data.frame 'eqn' : eqn <- data.frame(depy = I(as.matrix(dep)), indx = I(as.matrix(ind))) And run the PLSR package apls <- plsr(depy ~ indx, data=eqn) I seem to be getting either one of two error messages: [12] ERROR: invalid type (list) for variable 'dep' [13] ERROR: object of type 'closure' is not subsettable I'm sure now that this is a problem in my creation of data.frames, but can't seem to find anything that describes the problem ----- J.
