  pars,
  format = c("matrix", "array", "df", "list", "rvars")
)

Value

The posterior draws in the requested format.

Examples

if (FALSE) { # \dontrun{
befa_fit <- befa(
  data = HS_data, n_factors = 3, model = "cor",
  iter = 500, chains = 2, seed = 123
)

# Extract Lambda draws as a matrix
lambda_draws <- extract_posterior_draws(befa_fit, pars = "Lambda", format = "matrix")

# Extract as rvars for easy summaries
lambda_rvars <- extract_posterior_draws(befa_fit, pars = "Lambda", format = "rvars")
} # }
