I would like to extract the warmed up / sampling parameters using cmdstanr, in particular the step size. (I already have the inverse metric using fit$inv_metric()). After browsing Function reference • cmdstanr , I couldn’t find any function to get the sampler parameters. I know how to do this with r…

Ah, here it is fit$metadata() which included the adapted step size!

For posterity, the bug was worked out, and I also posted some code that achieves things properly.
