I am new to stans and I can’t figure out what this error is telling me when I try and run a brm model.
Version of R: 4.2
Rtools: 4.2

Error in compileCode(f, code, language = language, verbose = verbose) :

I think the error is pointing to something that went wrong with the installation. I am not sure if its from the installation of brms or rtools. Thank you for your help!

This issue is occurring because there are some compatibility issues with the version of rstan currently on CRAN. You can install the preview of the next rstan version using:

remove.packages(c("StanHeaders", "rstan"))
install.packages("StanHeaders", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))
install.packages("rstan", repos = c("https://mc-stan.org/r-packages/", getOption("repos")))

Alternatively, you could install the cmdstanr package and run your brms models with the backend = "cmdstanr" option
