l.calib | R Documentation |
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.
l.calib(yr, y, er, cc = ccurve(1, FALSE), normal = TRUE, t.a = 3, t.b = 4)
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 |
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). |
The function cannot deal with multiple calibration curves if multiple calendar years or radiocarbon dates are entered.
The calibrated probability of a calendar age for a 14C age

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
