Thanks to the RStudio developers, I have now been able to get RStan to work on RStudio Cloud. The default C++ compiler is g++, which consumes too much RAM when compiling a Stan program to fit into the 1GB limit imposed on users of this (free) service. However, that can be changed to clang++, in whic…

Not sure if you were planning on fixing this, but I note that there has been an update since I last posted. Nevertheless, I still have problems when trying to run the demos: > fit1 <- stan_demo(68) Do you want to download the example models? 1: Download to include directory of the rstan package 2…

It is still not working. I am trying to put together a customized version that utilizes less RAM.

Hello :) I want to prepare a course using brms and Rstudio Cloud, but I am unable to compile any model. I used the link in the first post of this thread, made a personnal copy and I tried with demos from stan_demo and with very simple models with only two parameters, but I always get this error me…

I have not been able to get much of anything to compile on RStudio Cloud with rstan >= 2.18 due to RAM limits. One option would be for me to ask the RStudio Cloud people to downgrade everything Stan related to 2.17. However, that is not great because recent versions of brms and related packages are …

Thank you for your response! I plan to use brms the 5th of april. It would be very convenient to use Rstudio cloud, because I always loose 10-15 minutes at the beginning of each session because of installation problems. However, I already used rstan in a session without the cloud, so I am not too …

In 2.18 we started using C++14 (or really C++11), which increased the amount of RAM needed to compile Stan programs, which is going to affect every conceivable and actual interface to Stan when constrained by a 1GB RAM limit.

Hi Ben, I took your class a couple of years ago. I noticed that the simple linear regression example on https://rstudio.cloud/project/56157 no longer works. It was working a few months ago, but now I get an error message. I’m wondering, are you aware of this issue ?

Hi Laura. Yes, I’m aware. At the moment, it is impossible to use RStudio Cloud with Stan, but I am hopeful that Bob’s refactor of the translation units will save RAM as well as compilation time, so that we can work within the 1GB limit that RStudio Cloud imposes.

One thought : is the problem related only to rstan? Would this problem be solved with a light R interface to Cmdstan?
