as_draws.CmdStanMCMC: Create a 'draws' object from a CmdStanR fitted model object

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

Create a draws object from a CmdStanR fitted model object

Description

Create a draws object supported by the posterior package. These methods are just wrappers around CmdStanR's $draws() method provided for convenience.

Usage

## S3 method for class 'CmdStanMCMC'
as_draws(x, ...)

## S3 method for class 'CmdStanMLE'
as_draws(x, ...)

## S3 method for class 'CmdStanLaplace'
as_draws(x, ...)

## S3 method for class 'CmdStanVB'
as_draws(x, ...)

## S3 method for class 'CmdStanGQ'
as_draws(x, ...)

## S3 method for class 'CmdStanPathfinder'
as_draws(x, ...)

Arguments

x	A CmdStanR fitted model object.
...	Optional arguments passed to the $draws() method (e.g., variables, inc_warmup, etc.).

Details

To subset iterations, chains, or draws, use the posterior::subset_draws() method after creating the draws object.

Examples

## Not run: 
fit <- cmdstanr_example()
as_draws(fit)

# posterior's as_draws_*() methods will also work
posterior::as_draws_rvars(fit)
posterior::as_draws_list(fit)

## End(Not run)
