chronos: Post-Processing of Markov Chain Monte Carlo Simulations for Chronological Modelling

Statistical analysis of archaeological dates and groups of dates. This package allows to post-process Markov Chain Monte Carlo (MCMC) simulations from 'ChronoModel' https://chronomodel.com/, 'Oxcal' https://c14.arch.ox.ac.uk/oxcal.html or 'BCal' https://bcal.shef.ac.uk/. It provides functions for the study of rhythms of the long term from the posterior distribution of a series of dates (tempo and activity plot). It also allows the estimation and visualization of time ranges from the posterior distribution of groups of dates (e.g. duration, transition and hiatus between successive phases). This package is an S4 rewrite of 'ArchaeoPhases' by Philippe and Vibet (2020) doi:10.18637/jss.v093.c01 .

Package options

chronos uses the following options() to configure behaviour:

• chronos.grid: a numeric value specifying the number of equally spaced points at which densities are to be estimated (defaults to \(512\)). Should be a power of \(2\).

• chronos.precision: an integer indicating the number of decimal places (defaults to \(0\)).

• chronos.progress: a logical scalar specifying if progress bars should be displayed (defaults to interactive()).
