Functions in rbacon (3.3.1)

accrate.depth.summary

Provide a summary of the estimated accumulation rates for any depth of a core.

Translate Bacon .csv files to clam .csv files.

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

accrate.age.summary

Provide a summary of the estimated accumulation rates for any age of a core.

calculate probabilities that Pb-210 data have reached background levels

accrate.depth.ghost

Plot modelled accumulation rates against the depths of a core.

Provide a summary of the estimated accumulation rates for a range of core depths

Add dates to age-depth plots

Plot an age-depth model

Extract one age-model iteration

Translate clam .csv files to Bacon .csv files.

Set initial values for the Bacon MCMC run.

Squeeze some 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.

Remove the first n iterations.

draw.pbmeasured

Plot the 210Pb data

Plot flux rates for proxies.

draw.pbmodelled

Plot the 210Pb data

Stretch some depths of a core

Bacon for vegans

Thin iterations.

Calculate modelled 210Pb

accrate.age.ghost

Plot a core's accumulation rates against calendar time.

Event probabilities against calendar age

Test to identify poorly mixed MCMC runs.

Output all depths for a single age.

Output all ages for a single depth.

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

Obtain estimated accumulation rates for any age of a core.

Main age-depth modelling function

Calculate age distributions of depths.
