Calculate C14 ages from pMC values of radiocarbon dates.
Usage
pMC.age(mn, sdev, ratio = 100, decimals = 0)
Value
Radiocarbon ages from pMC values. If pMC values are above 100%, the resulting radiocarbon ages will be negative.
Arguments
mn
Reported mean of the pMC.
sdev
Reported error of the pMC.
ratio
Most modern-date values are reported against 100. If it is against 1 instead, use 1 here.
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.
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\%)
