Hi all, I’m running into an error I haven’t seen before - I’m sure there is a simple fix but I haven’t found any solutions and there are next to no mentions online. The error is: “Found an incomplete binary expression - are you missing the right hand side?”

The code generating the error is:

```
transformed parameters{
vector[N] res;
res[1] = 0;
for(n in 2:N){
res[n] = f_pass[n-1] - (beta[1] * s_elev[n-1] + beta[2] * dop[n-1] + beta[3] * dop[n-1]^2 + beta[4] * s_mt[n-1] + beta[5] * s_cumics[n-1] + int + u[year[n-1]] + res[n-1] + f_rem[n-1]);
}
}
```

Specifically, the line of code generating the error is the single line held within the for loop.

Thanks for the help!
