Converts F14C values to 14C ages.

Usage

BP14C_to_F14C(ages, errors, ...)

F14C_to_BP14C(values, errors, ...)

# S4 method for numeric,numeric
BP14C_to_F14C(ages, errors, lambda = 8033)

# S4 method for numeric,numeric
F14C_to_BP14C(values, errors, lambda = 8033, asymmetric = FALSE)

Arguments

ages

A numeric vector giving the radiocarbon ages.

errors

A numeric vector giving the standard deviations.

...

Currently not used.

values

A numeric vector giving the F14C values.

lambda

A length-one numeric vector specifying the mean-life of radiocarbon (defaults to 14C half-life value as introduced by Libby 1952).

asymmetric

A logical scalar: should asymmetric 14C errors be returned?

Value

A data.frame.
