F14CtoC14 {rice} | R Documentation |
Calculate C14 ages from F14C values.
Description
Calculate C14 ages from F14C values of radiocarbon dates.
Usage
F14CtoC14(F14C, er = NULL, decimals = 5, lambda = 8033)
Arguments
F14C |
Reported mean of the F14C |
er |
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 (between 0 at c. 55 kcal BP and 1 at c. AD 1950). Since software such as Bacon expects radiocarbon ages, this function can be used to calculate radiocarbon ages from F14C values. The reverse function is age.F14C.
Value
The radiocarbon ages from the F14C values. If F14C values are above 100%, the resulting radiocarbon ages will be negative.
Examples
F14CtoC14(1.10, 0.5) # a postbomb date, so with a negative C14 age
F14CtoC14(.80, 0.5) # prebomb dates can also be calculated
