My guess is that it will be OK if you have the V8 package installed, in which case it will try to use that rather than QuickJSR. But we have...

That combination is working on CRAN. Possibly you have a different version of V8 than what they are using. We'll see what happens once StanHeaders 2.32.x goes up (its Javascript...

We're close enough on rstan that I believe we will have time to convert rstanarm to the new rstantools and array syntax by the 13th. On Thu, Aug 31, 2023...

We have https://github.com/stan-dev/math/pull/2720 but it is not quite ready yet.

For any rootfinder, you would want to implicitly differentiate at the end to get the derivatives with respect to any unknown parameters. You could autodiff through things like Newton iterations...

Yes, although StanHeaders and / or rstanarm are more critical at the moment.

This is unrelated to the rstan issue with the javascript parser not preserving blank lines, but whatever. Has anyone gotten a notice from CRAN saying their package is subject to...
