 Plotting functions for posterior analysis, model checking,
 and MCMC diagnostics. The package is designed not only to provide convenient
 functionality for users, but also a common set of functions that can be
 easily used by developers working on a variety of R packages for Bayesian
 modeling, particularly (but not exclusively) packages interfacing with 'Stan'.
