Brms without rStan but with CmdStanR?

Hi, my R does not have rStan because I could not get the Makevars to work. Instead, I use CmdStanR and it works.

The Brms package seems to require rStan to function properly. Please correct me if I am wrong. I also see that Brms has a backend option with CmdStan, but I need to research more on this. Can I install and run Brms properly on my machine? Thanks

Follow-up on Friendly Mac C++ installer does not work for me

Yup. You just need to install both brms & cmdstanr, run cmdstanr::install_cmdstan(), then use the backend argument when using brms::brm() thereafter, for example:

brms::brm( 
    ... # model stuff here
    , backend = "cmdstanr"
)
