ananke (version 0.1.0)

F14C: F14C

Description

Converts F14C values to 14C ages.

Usage

BP14C_to_F14C(values, errors, ...)
F14C_to_BP14C(values, errors, ...)
# S4 method for numeric,numeric
BP14C_to_F14C(values, errors, lambda = 8033)
# S4 method for numeric,numeric
F14C_to_BP14C(
  values,
  errors,
  lambda = 8033,
  asymmetric = FALSE,
  rounding = getOption("ananke.round")
)

Value

A data.frame.

Arguments

values

A numeric vector giving the radiocarbon ages or the F14C values.

errors

A numeric vector giving the standard deviations.

...

Currently not used.

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 (van der Plicht & Hogg, 2006)?

rounding

A character string specifying the rounding convention. It can be one of "none" (the default, no rounding) or "stuiver". Any unambiguous substring can be given.
