Transforms 'raw' radiocarbon ages into a calendar probability distribution using a calibration curve.

Usage

c14_calibrate(
  c14_age,
  c14_error,
  ...,
  engine = c("intcal", "rcarbon", "oxcal", "bchron")
)

Arguments

c14_age

Vector of uncalibrated radiocarbon ages.

c14_error

Vector of standard errors associated with c14_age.

...

Optional arguments passed to calibration function (see below).

engine

Method to use for calibration. The default ("intcal") is fast and simple. Other options require additional packages to be installed. Available engines:

Value

A list of cal objects.

Details

c14_age and c14_error are recycled to a common length.

Parallelisation is supported for engines "intcal" and "rcarbon" and can dramatically speed up calibration of large numbers of dates. For "intcal", it must first be enabled with future::plan(). For "rcarbon", it requires the doSNOW package and can be controlled with the ncores argument of rcarbon::calibrate().
