pMCtoC14: Calculate C14 ages from pMC values.

In rice: Radiocarbon Equations

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
