I am unable to install rstan in Colab.
Open a notebook:
enter these cells ( or copy the notebook and run that)
rstan does not install. When I execute the r code, this is the error.
Error in library(“rstan”): there is no package called ‘rstan’
Any thoughts? Thanks so much in advance.
you should be able to use CmdStanR on colab.
I wrote some CmdStanR Colab examples when we were at CmdStan 2.23 - you should be able to use 2.24.1 by now (and soon, 2.25.0!):
examples for calculating Covid rate - Santa Clara study of spring 2020: https://github.com/stan-dev/example-models/tree/master/jupyter/covid-inf-rate
case study: https://mc-stan.org/users/documentation/case-studies/jupyter_colab_notebooks_2020.html
looked at your notebook -
system("apt install -y r-cran-rstan") - any complaints or warnings?
Thanks. The CmdStanR Colab examples all work on my end. Still can’t get the notebook to work using the approach I sent. No warnings or anything else printed when this executes:
system("apt install -y r-cran-rstan")
Not really sure. Thanks again.
