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:"intcal"
:IntCal::caldist()
(default)"rcarbon"
:rcarbon::calibrate()
"oxcal"
:oxcAAR::oxcalCalibrate()
"bchron"
:Bchron::BchronCalibrate()
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()
.
