Import certain parameters from cmdstan .csv output files to Stanfit object

[rok_cesnovar]

I dont think you can make a stanfit from that, but you can traceplot from cmdstanr easily.

Example:

f <- cmdstanr::read_cmdstan_csv(files, variables = c("mu", "nu"))
bayesplot::mcmc_trace(f$post_warmup_draws[,,c("mu", "nu")])

A different example:

Import csv output from cmdstan in R: How to indicate the chain?

I am not sure how you can do that with rstan’s functions but this work for cmdstan output and traceplots: # install.packages("remotes") remotes::install_github("stan-dev/cmdstanr") library(cmdstanr) library(bayesplot) fit <- as_cmdstan_fit(files) color_scheme_set("mix-blue-pink") mcmc_trace(fit$draws(variables = c("alpha", "beta[1]"))) [image]
