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?

Any input will be greatly appreciated.

Thank you very much, in advance.

Payam
