Getting started

[JWSBayes]

I am using RStudio Version 1.2.5042 and R 4.0.0.

I have installed RStan.

I started by trying to run the schools.stan example in : https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started

When I do this, RStudio hangs. When I break-in and “Stop” R, I get the following message:
Error in sink(type = “output”) : invalid connection.

I do not know what this means or have a good understanding of what is meant by “sink”.

Does anyone have any advice on how to proceed?

Thanks,

John
