Examples

if (FALSE) { # \dontrun{
# example with return codes all zero
fit_mcmc <- cmdstanr_example("schools", method = "sample")
fit_mcmc$return_codes() # should be all zero

# example of non-zero return code (optimization fails for hierarchical model)
fit_opt <- cmdstanr_example("schools", method = "optimize")
fit_opt$return_codes() # should be non-zero
} # }
