pMCtoC14 {rice} | R Documentation |
Calculate C14 ages from pMC values.
Description
Calculate C14 ages from pMC values of radiocarbon dates.
Usage
pMCtoC14(pMC, er = NULL, decimals = 0, lambda = 8033)
Arguments
pMC |
Reported mean of the pMC. |
er |
Reported error of the pMC. |
decimals |
Amount of decimals required for the radiocarbon age. |
lambda |
The mean-life of radiocarbon (based on Libby half-life of 5568 years) |
Details
Post-bomb dates are often reported as pMC or percent modern carbon. Since Bacon expects radiocarbon ages, this function can be used to calculate radiocarbon ages from pMC values. The reverse function is C14.pMC.
Value
Radiocarbon ages from pMC values. If pMC values are above 100%, the resulting radiocarbon ages will be negative.
Examples
pMCtoC14(110, 0.5) # a postbomb date, so with a negative 14C age
pMCtoC14(80, 0.5) # prebomb dates can also be calculated
pMCtoC14(.8, 0.005) # throws a warning, use F14C.age instead
