l.calib {rintcal}

Find the calibrated probability of a calendar age for a 14C date.

Description

Find the calibrated probability of a cal BP age for a radiocarbon date. Can handle either multiple calendar ages for a single radiocarbon date, or a single calendar age for multiple radiocarbon dates.

Usage

l.calib(yr, y, er, cc = ccurve(1, FALSE), normal = TRUE, t.a = 3, t.b = 4)

Arguments

yr

The cal BP year.

y

The radiocarbon date's mean.

er

The radiocarbon date's lab error.

cc

calibration curve for the radiocarbon date(s) (see ccurve()).

normal

Use the normal distribution to calibrate dates (default TRUE). The alternative is to use the t model (Christen and Perez 2016).

t.a

Value a of the t distribution (defaults to 3).

t.b

Value b of the t distribution (defaults to 4).

Details

The function cannot deal with multiple calibration curves if multiple calendar years or radiocarbon dates are entered.

Value

The calibrated probability of a calendar age for a 14C age

Examples

l.calib(100, 130, 20)
l.calib(100:110, 130, 20) # multiple calendar ages of a single date
l.calib(100, c(130,150), c(15,20)) # multiple radiocarbon ages and a single calendar age
