rstan::stan_version()
[1] “2.17.0”

I’ve tried various combinations of remove.packages("rstan") and restarting RStudio, as well as doing install.packages("rstan", type = "source"). Any ideas?

The stan_version function pertains to the upstream major version. You want packageVersion("rstan")

Ah, I misread the release notes. Reading them again, how would I try 2.17.1? The reason this came up is that I don’t seem to have access the new-ish append_array function, so I thought maybe I had an out of date Stan. (The release notes say append_array is in 2.17.0, but, yeah, thought it was a possibility.) E.g.

No matches for: 

  append_array(int[], int[])

Function append_array not found.

There isn’t a StanHeaders on CRAN that has that yet. You would have to install the “for-2.18” branch of rstan and StanHeaders from GitHub.

Awesome, thank you for your help!
