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
