Error: An error occured during compilation! See the message above for more information.
In addition: Warning messages:

Start with the generated Stan snippet around line 10 and the cmdstan_model(stan.f.name) call, then check the relevant RStan and Stan versions. Reproduce the compilation failure and identify a documented, verifiable cause or correction for the reported parsing error.
