Description

I’m running stan.R and it’s great! But now I really really want it to do that thing where, after running 1/20 of the iterations, it prints an estimate of total runtime. Which will typically be a conservative estimate because adaptation takes longer than regular runs. Then also it would be good to spit out total elapsed time when it's all done.

Ideally this info would be produced by Stan (not Rstan) so this is really a more general request.

Research direction

Start with stan.R and trace how iteration progress and completion are reported. Confirm whether the timing information belongs in Stan rather than RStan; done means reporting an estimated total runtime after roughly 1/20 of the iterations and total elapsed time when sampling finishes.
