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?
