We propose new statistical tools to analyze and to estimate archeological phases from the posterior distribution of a sequence of dates. All the functions are implemented in the R package RChronoModel. The required inputs are simulated samples from the posterior distribution of the dates. Such MCMC samples are provided, for instance, by ChronoModel or Oxcal, two softwares build for the chronological modeling of archeological dates. We give a practical introduction to the package RChronoModel using published data and comment the statistical results.
