You can use list() to return multiple outputs. Thomas Sander wrote: Kris -- Many thanks. Have you or other had experience in R with an error message on running a function that says ............: multi-argument returns are deprecated I've written an OLS function that is returning three outputs (coeff, sigmahatsq, u). Is that illegal in R? Do I need to write three separate OLS functions: one that returns the Betas, one that returns sigma-hat squared and one that returns u? Many thanks. Best.
