Calibrated radiocarbon dates

The cal class represents a vector of calibrated radiocarbon dates as a lazy record. Each element stores the parameters needed to derive a calendar probability distribution (c14_age, c14_error, and c14_curve), but does not compute the distribution until requested.

Usage

cal(c14_age = double(), c14_error = double(), curve = c14_curve())

Arguments

c14_age

Vector of uncalibrated radiocarbon ages.

c14_error

Vector of standard errors associated with c14_age.

curve

A c14_curve object or list of c14_curve objects. Default: IntCal20.

Value

A vector of class cal (c14_cal).

Examples

cal(1000, 30, curve = IntCal20)
#> <c14_cal[1]>
#> [1] 797–956 cal BP
cal(c(1000, 2000), c(30, 40), curve = IntCal20)
#> <c14_cal[2]>
#> [1]   797–956 cal BP 1827–2044 cal BP
