calBP.14C: Find the 14C age and error belonging to a cal BP age.

In GPawi/clamsy: Classical Age-Depth Modelling of Cores from Deposits

Description

From a given calendar ages, the calibration curve (default cc=1) is interpolated and the corresponding 14C age and error is returned.

Usage

calBP.14C(
  yr,
  cc = 1,
  cc1 = "IntCal13.14C",
  cc2 = "Marine13.14C",
  cc3 = "SHCal13.14C",
  cc4 = "mixed.14C",
  ccdir = "",
  postbomb = FALSE,
  pb1 = "postbomb_NH1.14C",
  pb2 = "postbomb_NH2.14C",
  pb3 = "postbomb_NH3.14C",
  pb4 = "postbomb_SH1-2.14C",
  pb5 = "postbomb_SH3.14C"
)

Arguments

yr	The cal BP year.
cc	calibration curve for C14 dates (1, 2 or 3).
cc1	For northern hemisphere terrestrial C14 dates.
cc2	For marine C14 dates.
cc3	For southern hemisphere C14 dates.
cc4	A custom calibration curve
ccdir	Directory where the calibration curves for C14 dates cc are allocated. By default ccdir="". Use ccdir="." to choose current working directory. Use ccdir="Curves/" to choose sub-folder Curves/.
postbomb	Which postbomb curve to use for negative 14C dates
pb1	For Northern hemisphere region 1 postbomb C-14 dates.
pb2	For Northern hemisphere region 2 postbomb C-14 dates.
pb3	For Northern hemisphere region 3 postbomb C-14 dates.
pb4	For Southern hemisphere regions 1-2 postbomb C-14 dates.
pb5	For Southern hemisphere region 3 postbomb C-14 dates.

Details

Interpolation is used, and values outside the calibration curve are given as NA. For negative cal BP ages, a postbomb curve will have to be provided.
