Project Status: Active – The project has reached a stable, usable state and is being actively developed.

Overview

Datasets for chronological modelling with chronos. This package provides models and data to reproduce results from chronos examples and vignettes.

Installation

You can install the latest version of fasti from our repository with:

install.packages("fasti", repos = "https://tesselle.r-universe.dev")

Usage

The inst/ directory contains:

  • ChronoModel v2.0.18 project files and output files (in the chronomodel/ subdirectory).
  • OxCal v4.4.4 script and output files (in the oxcal/ subdirectory).
  • BCal output files (in the bcal/ subdirectory).

ChronoModel

This package allows to replicate the following results:

  • ksarakil: chronology of Ksâr’Akil (Lebanon) – Bosch et al.
  • lezoux: chronology of a potter’s kiln from Lezoux (France) – Menessier-Jouannet et al. (1995)
## Install chronos
# install.packages("chronos")
library(chronos)

## Import ChronoModel output
lezoux_path <- system.file("chronomodel/lezoux/Chain_all_Events.csv", 
                           package = "fasti")
lezoux_event <- read_chronomodel_events(lezoux_path, sep = ";", dec = ",")

## Plot MCMC sample
plot(lezoux_event, interval = "hpdi")

OxCal

This package allows to replicate Bosch et al. (2015) results with OxCal (and ChronoModel).

## Install and load oxcAAR
# install.packages("oxcAAR")
library(oxcAAR)

## Download and setup OxCal
quickSetupOxcal()

## Import the OxCal script
path_script <- system.file("oxcal/ksarakil.oxcal", package = "fasti")
ksarakil_script <- paste0(readLines(path_script), collapse = "\n")

## Execute OxCal
ksarakil_file <- executeOxcalScript(ksarakil_script)
ksarakil_text <- readOxcalOutput(ksarakil_file)
ksarakil_data <- parseFullOxcalOutput(ksarakil_text)

## Get the MCMC samples
path_mcmc <- paste0(dirname(ksarakil_file), "/MCMC_Sample.csv")
mcmc <- read.csv(path_mcmc, header = TRUE, sep = ",", dec = ".")
