rbacon (version 2.3.9.1)

Age-Depth Modelling using Bayesian Statistics

Description

Bacon is an approach to age-depth modelling that uses Bayesian statistics to reconstruct accumulation histories for deposits, through combining radiocarbon and other dates with prior information. See Blaauw & Christen (2011) .

Functions in rbacon (2.3.9.1)

Event probabilities against calendar age

Test to identify poorly mixed MCMC runs.

accrate.age.ghost

Plot a core's accumulation rates against calendar time.

Obtain estimated accumulation rates as for any depth of a core.

Obtain estimated accumulation rates for any age of a core.

Remove files made to produce the current core's age-depth model.

Calculate age distributions of depths.

List the folders present in the current core directory.

Main age-depth modelling function

Output all ages for a single depth.

Plot flux rates for proxies.

copyCalibrationCurve

Copy a calibration curve.

accrate.depth.ghost

Plot modelled accumulation rates against the depths of a core.

Proxies analysed along the depths of a core can be plotted as 'proxy-ghost' graphs against calendar time while taking into account chronological uncertainties. Here darker grey indicates more likely calendar ages for specific proxy values.

Add dates to age-depth plots

Calculate C14 ages from pMC values.

Build a custom-made, mixed calibration curve.

Extract one age-model iteration

Calculate pMC values from C14 ages

Plot an age-depth model

Remove the first n iterations.

Thin iterations.
