Convert a Coda object to a tibble with specified parameter transformations

This function converts a Coda object (mcmc.list or mcmc) into a tibble format, facilitating further analysis and visualisation. It supports transformation for specific parameter types: rho, alpha, omega, and beta.

Usage

coda_to_tibble(
  coda_object = NULL,
  posterior_type = NULL,
  env_file = ".env",
  n_omega = 100
)

Arguments

coda_object

An object of class mcmc.list or mcmc, representing the MCMC output.

posterior_type

Character. The parameter type to transform and extract. Must be one of rho, alpha, omega, or beta.

env_file

Character. Path to the environment file containing paths to data sources. Defaults to .env.

n_omega

Integer. The number of species to be sampled for the Omega parameter transformation. Defaults to 100.

Value

A tibble containing the transformed parameters based on the specified posterior_type. The structure of the returned tibble varies depending on the posterior_type parameter.
