No, it only downloads and installs the right compilers and updates
Makevars and REnvirons. These are what Stan and RCpp require so you could
do these manually.
What it does is described at https://github.com/rmacoslib/r-macos-rtools

Thank you very much to all.
Does Installing the macos-rtools could affect R in other ways?

What worked for me was installing the tools using
and then installing rstan from source ie
install.packages(?rstan?,type=?source) as suggested on one of the stan

Dear list members,
When trying to fit this example from the CRAN repository fro brms, I
the following error message after the 4th chain. I am using R 3.6.1 in
Catalina MacOS.
library(brms)
group <- rep(c("treat", "placebo"), each = 30)
symptom_post <- c(rnorm(30, mean = 1, sd = 2), rnorm(30, mean = 0, sd
dat1 <- data.frame(group, symptom_post)
fit1 <- brm(bf(symptom_post ~ group, sigma ~ group),
data = dat1, family = gaussian())
[1] "Error in sampler$call_sampler(args_list[[i]]) : "
[2] " c++ exception (unknown reason)"
error occurred during calling the sampler; sampling not done
I think is a problem with Catalina MacOS, but I don?t know how to
Manuel
