fit-method-output: Access console output

In stan-dev/cmdstanr: R Interface to 'CmdStan'

Access console output

Description

For MCMC, the ⁠$output()⁠ method returns the stdout and stderr of all chains as a list of character vectors if id=NULL. If the id argument is specified it instead pretty prints the console output for a single chain.

For optimization and variational inference ⁠$output()⁠ just pretty prints the console output.

Usage

output(id = NULL)

Arguments

id	(integer) The chain id. Ignored if the model was not fit using MCMC.
