l.calib: 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 = rintcal::ccurve(1, FALSE),
normal = TRUE,
as.F = FALSE,
t.a = 3,
t.b = 4
)
Value
The calibrated probability of a calendar age for a 14C age
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 the rintcal package).
normal
Use the normal distribution to calibrate dates (default TRUE). The alternative is to use the t model (Christen and Perez 2016).
as.F
Whether or not to calculate ages in the F14C realm. Defaults to as.F=FALSE, which uses the C14 realm.
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.
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
