⚠️There's a newer version (3.3.1) of this package.Take me there.

rbacon (version 2.3.3)

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 (2.3.3)

add.dates

Add dates to age-depth plots

Bacon.Age.d

Output all ages for a single depth.

AgesOfEvents

Event probabilities against calendar age

pMC.age

Calculate C14 ages from pMC values.

accrate.depth.ghost

Plot modelled accumulation rates against the depths of a core.

thinner

Thin iterations by given proportion, for example if autocorrelation is visible within the MCMC series, and then update the output file.

proxy.ghost

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.

accrate.age

Obtain estimated accumulation rates for any age of a core.

scissors

Remove the first n iterations.

rbacon

Bacon.hist

Calculate age distributions of depths.

agedepth

Plot an age-depth model

age.pMC

Calculate pMC values from C14 ages

Bacon

Main age-depth modelling function

mix.curves

Build a custom-made, mixed calibration curve.

Bacon.cleanup

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

flux.age.ghost

Plot flux rates for proxies.

calib.plot

Plot the dates

accrate.depth

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

accrate.age.ghost

Plot a core's accumulation rates against calendar time.

copyCalibrationCurve

Copy a calibration curve.

Baconvergence

Test to identify poorly mixed MCMC runs.

Bacon_runs

List the folders present in the current core directory.
