pMC.age {IntCal} | R Documentation |
Calculate C14 ages from pMC values.
Description
Calculate C14 ages from pMC values of radiocarbon dates.
Usage
pMC.age(mn, sdev, ratio = 100, decimals = 0)
Arguments
mn |
Reported mean of the pMC. |
sdev |
Reported error of the pMC. |
ratio |
Most modern-date values are reported against |
decimals |
Amount of decimals required for the radiocarbon age. |
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 age.pMC.
Value
Radiocarbon ages from pMC values. If pMC values are above 100%, the resulting radiocarbon ages will be negative.

Examples
pMC.age(110, 0.5) # a postbomb date, so with a negative 14C age
pMC.age(80, 0.5) # prebomb dates can also be calculated
pMC.age(.8, 0.005, 1) # pMC expressed against 1 (not against 100\%)
