Usage

backend_draws_array(raw_fit)

Arguments

raw_fit

a backend-native fit object (an rstan stanfit or a cmdstanr CmdStanMCMC).

Value

a 3-D array, dimensions iterations x chains x parameters.

Examples

if (FALSE) { # \dontrun{
draws <- backend_draws_array(fit)
dim(draws) # iterations x chains x parameters
} # }
