I dont think I set that. I remember seeing this [thread](https://discourse.mc-stan.org/t/problems-getting-stan-to-run-after-upgrading-to-r-4-0-2/17896/6) specifically saying to “unlist” .rprofile.

I’ve also tried all sorts of answers from differrnt threads hoping something would stick so maybe that was done by accident.

The example code now works! Thanks so much

example code:  
example(stan\_model, package = “rstan”, run.dontrun = TRUE)
