Hi,

I was wondering if anyone might know about this. I was running a simple multilevel model and it would crash my R. My R version is 3.6.3. It’s a simple example of brms and it would pop the error message “R abort session”. I thought it’s something to do with my R version so I went to RStudio.cloud and run it with version 3.6. I only installed brms and nothing else on the RStudio.cloud. However, it’s still crashed and gave me the following feedback. This is the first time over 2 years I run into such incident when using rstan and brms.

Best wishes

Lawrence

It happens to me too when the model is heavy :(

If the model was too heavy, I’d take the error happily. But then it’s just a small one and it’s the example from the brms package, so I assume it should be fairly light. First time, really.
