issue while Using 'Rstan' Package in R


It seems the error message tells you to submit this question to the Rstan's GitHub page, so I should do that rather than here :slight_smile:

Also, if you like us to help debugging code, please provide us with a reprex next time. A reprex consists of the minimal code and data needed to recreate the issue/question you're having. You can find instructions how to build and share one here:
