Radiocarbon calibration of Bchron data

Description

Runs standard radiocarbon calibration of determinations.

Usage

Bchroncalibrate(Bchrondata, iterations = 5e+05, burnin = 50000, thinby = 45, howmany = 50000, defaults = FALSE)

Arguments

Bchrondata A Bchron data object with fields for the the input and output files, the name of the core being used, the details of the calibration curve, and details of the model run required. See Bchronload and Bchronmenu for more details.
iterations Number of MCMC iterations required. Default is 500,000.
burnin Number of discarded burn-in iterations. Default is 50,000.
thinby Step size of iterations to thin out. Default is to take every 45th iteration.
howmany Number of iterations before R reports back and updates the screen. Default is 50000
defaults If true, runs Bchroncalibrate without any warnings and overwrites previous runs. If FALSE (default) will prompt user before continuing.

Details

This function run simple radiocarbon calibration of each of the determinations individually without any chronology constraint. The results here should be directly comparable with those obtained from, eg Oxcal, Bcal, Calib, etc.

Value

No specific value is returned but two files are created in the output directory, giving the raw radiocarbon calibrated age iterations (corenameTrueDates.txt) and a summary of the 2.5
