It does not work in the construction I have here and I do not know why. Dear expeRts, I am struggling with warning/error handling. In cases where a warning is harmless, the code in question can be wrapped with `suppressWarnings()`. this needs to be done in mle_1ply and bayes_simple_1ply in particular.
