universals

universals provides S3 generic methods and some default implementations for Bayesian analyses that generate Markov Chain Monte Carlo (MCMC) samples.

The purpose of universals is to reduce package dependencies and conflicts.

Philosophy

The methods are primarily designed to be used for Bayesian analyses that generate Markov Chain Monte Carlo (MCMC) samples but many can also be used for Maximum Likelihood (ML) and other types of analyses.

The names of the functions are based on the following definitions/concepts:

• A term is a single real or integer value.
• A par (short for parameter) is a numeric object of terms.
• An MCMC object is a collection of MCMC samples that refer to a set of terms.
• The samples are arranged in one or more chains of the same length (number of iterations).
• The number of simulations is the product of the number of iterations and the number of chains.
• The number of samples is the product of the number of simulations and the number of terms.

The ‘nlist’ package implements many of the methods for its ‘nlists’ class.

Installation

To install the latest release from CRAN

install.packages("universals")

To install the developmental version from GitHub

# install.packages("remotes")
remotes::install_github("poissonconsulting/universals")

Usage

universals is designed to be used by package developers.

It is recommended to import and re-export the generics of interest. For example, to provide a method for the S3 pars() method, use the following roxygen2 code:

#' @importFrom universals pars
#' @export
universals::pars
