Examples

# \donttest{
ex <- mcmcsae_example(n=50)
sampler <- create_sampler(ex$model, data=ex$dat)
sim <- MCMCsim(sampler, burnin=100, n.iter=300, thin=2, n.chain=5, store.all=TRUE)
n_chains(sim); n_chains(sim$beta)
n_draws(sim); n_draws(sim$beta)
n_vars(sim$beta); n_vars(sim$sigma_); n_vars(sim$llh_); n_vars(sim$v)
plot(sim, "beta")
n_chains(subset(sim$beta, chains=1:2))
n_draws(subset(sim$beta, draws=sample(1:n_draws(sim), 100)))
n_vars(subset(sim$u, vars=1:2))
