Functions in rbacon (3.1.1)

Bacon.cleanup

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

Bacon.Age.d

Output all ages for a single depth.

A.modelled

Calculate modelled 210Pb

AgesOfEvents

Event probabilities against calendar age

accrate.age.ghost

Plot a core's accumulation rates against calendar time.

add.dates

Add dates to age-depth plots

Bacon.d.Age

Output all depths for a single age.

agedepth

Plot an age-depth model

bacon2clam

Translate Bacon .csv files to clam .csv files.

Test to identify poorly mixed MCMC runs.

agemodel.it

Extract one age-model iteration

accrate.depth

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

squeeze

Squeeze some depths of a core

flux.age.ghost

Plot flux rates for proxies.

accrate.depth.ghost

Plot modelled accumulation rates against the depths of a core.

background

calculate probabilities that Pb-210 data have reached background levels

scissors

Remove the first n iterations.

stretch

Stretch some depths of a core

Bacon

Main age-depth modelling function

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.

rbacon

set.initvals

Set initial values for the Bacon MCMC run.

clam2bacon

Translate clam .csv files to Bacon .csv files.

Calculate age distributions of depths.

accrate.age

Obtain estimated accumulation rates for any age of a core.
