Hello.

I just updated to most recent version of stan using instructions here:

I’m running r ‘your stupid darkness’ on a MacBook Pro OSX 10.12.5

I’ve used this code before this update. However now it says 'Error in myglmer2stan(mod:  
Could not find function “myglmer2stan”

Though I have it installed.

Thoughts?

The `myglmer2stan` function does not come with RStan. Richard McElreath had a prototype `glmer2stan` function before he wrote his rethinking package, and people tried variations on the `glmer2stan` idea. So, the function you are referring to is probably in another package that you have installed locally, but it is typically better to use the `stan_glmer` function in the **rstanarm** package or the `brm` function in the **brms** package to execute those sorts of models.

I think it is unmaintained for several years. Use `rstanarm::stan_glmer` or `brms::brm` or `rethinking::map2stan`.
