F14C.age {rintcal}

Calculate C14 ages from F14C values.

Description

Calculate C14 ages from F14C values of radiocarbon dates.

Usage

F14C.age(mn, sdev = c(), decimals = 5, lambda = 8033)

Arguments

mn

Reported mean of the F14C

sdev

Reported error of the F14C. Returns just the mean if left empty.

decimals

Amount of decimals required for the radiocarbon age. Quite sensitive, defaults to 5.

lambda

The mean-life of radiocarbon (based on Libby half-life of 5568 years)

Details

Post-bomb dates are often reported as F14C or fraction modern carbon. Since Bacon expects radiocarbon ages, this function can be used to calculate radiocarbon ages from F14C values. The reverse function is age.F14C.

Value

Radiocarbon ages from F14C values. If F14C values are above 100%, the resulting radiocarbon ages will be negative.

Examples

  F14C.age(1.10, 0.5) # a postbomb date, so with a negative 14C age
  F14C.age(.80, 0.5) # prebomb dates can also be calculated
