CtoF: Calculate F14C values from C14 ages

In rice: Radiocarbon Equations

Calculate F14C values from C14 ages

Description

Calculate F14C values from radiocarbon ages

Usage

CtoF(y, er = NULL, roundby = NA, lambda = 8033, botherrors = FALSE)

Arguments

y	Reported mean of the 14C age.
er	Reported error of the 14C age. If left empty, will translate y to F14C.
roundby	Amount of decimals required for the output. Defaults to roundby=NA, no rounding.
lambda	The mean-life of radiocarbon (based on Libby half-life of 5568 years).
botherrors	Since going from C14 to F14C involves a logarithmic transformation (F=exp(-y/lambda)), errors that are symmetric on the C14 scale will become asymmetric on the F14C scale. By default, only the largest error is reported, but if botherrors=TRUE, both errors are reported.

Details

Post-bomb dates are often reported as F14C or fraction modern carbon. Since software such as Bacon expects radiocarbon ages, this function can be used to calculate F14C values from radiocarbon ages. The reverse function of F14C.age. This function is a shortcut to C14toF14C.

Value

F14C values from C14 ages.

Examples

  CtoF(-2000, 20)
