Error in rstan

[mansillo]

So I suspect this

@mansillo

I get this:

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

was not what you were after when you said this:

@bgoodri

OK. That is a different problem then. What does

library(rstan)
example(stan_model, run.dontrun = TRUE)

output on the line that has error: in it (with the colon)?

I’m not feeling like the sharpest tool in the shed at the moment so please bear with me (and you have my utter thanks).

Yesterday I was getting these errors then did something to Makevars and when I tried to run a model in brms the errors were the same as this:

@torkar

Hi

I upgraded by mistake :( Well, I fired up RStudio and ran my script I worked on yesterday (after having updated Xcode and the command line tools, and accepting the license agreement). Now, I get an error.

I use brms and it compiles and starts sampling but then during warmup I get this:

Chain 2: Iteration: 1 / 2000 [ 0%] (Warmup)
[1] “Error in sampler$call_sampler(args_list[[i]]) : "
[2] " c++ exception (unknown reason)”
error occurred during calling the sampler; sampling not done

I tried to reinstall rstan and then the error I am querying reappeared.

My workflow is mostly in brms now so I am at a bit of a loss about how the fix_Mac function could work.

Is there anything I do to help?
