Functions in rbacon (3.2.0)

bacon2clam

Translate Bacon .csv files to clam .csv files.

add.dates

Add dates to age-depth plots

agedepth

Plot an age-depth model

scissors

Remove the first n iterations.

set.initvals

Set initial values for the Bacon MCMC run.

calib.plot

Plot the dates

accrate.depth.ghost

Plot modelled accumulation rates against the depths of a core.

accrate.depth

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

squeeze

Squeeze some depths of a core

stretch

Stretch some depths of a core

Plot flux rates for proxies.

background

calculate probabilities that Pb-210 data have reached background levels

agemodel.it

Extract one age-model iteration

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

Bacon

Main age-depth modelling function

draw.pbmeasured

Plot the 210Pb data

clam2bacon

Translate clam .csv files to Bacon .csv files.

A.modelled

Calculate modelled 210Pb

accrate.age

Obtain estimated accumulation rates for any age of a core.

Bacon.d.Age

Output all depths for a single age.

Bacon.hist

Calculate age distributions of depths.

Bacon.cleanup

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

Bacon.Age.d

Output all ages for a single depth.

accrate.age.ghost

Test to identify poorly mixed MCMC runs.

AgesOfEvents

Event probabilities against calendar age
