# R bchron

Bchron functions. The most important functions are BchronCalibrate to calibrate radiocarbon (and non-radiocarbon) dates, Bchronology for the age-depth model of Haslett and Parnell (2008), BchronRSL to get rate estimates for relative sea level data, BchronDensity and BchronDensityFast for non-parametric phase modelling of age data.

Locate your Bchron directory, and select IntCal04.bch as your calibration curve and Glen-dalough.dat as your input ﬁle. All other options can be left as default. 4. Now choose option 2 to calibrate the radiocarbon dates. 5. Bchron is a Bayesian chronology model implemented in R. Arguments dates.

A vector of ages (most likely 14C) ageSds. A vector of 1-sigma values for the ages given above. calCurves. A vector of values containing either intcal20, shcal20, marine20, or normal (older calibration curves such as intcal13 are also supported). BChron-related functions. runBchron() Generate a Bayesian Reconstruction Age Model (Bacon) and add it into a LiPD object.

## Depths were related to ages using the Bchron package (Haslett and Parnell, 2008; Parnell et al., 2008) for R, and plots were made using SigmaPlot® software .

Single or multiple radiocarbon dates can be calibrated using the calibrate() function, which uses the probability density approach (see Bronk Ramsey 2008) implemented in most calibration software (e.g.
