mix.calibrationcurves: Build a custom-made, mixed calibration curve.

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

Description

If two curves need to be 'mixed' to calibrate, e.g. for dates of mixed terrestrial and marine carbon sources, then this function can be used.

Usage

mix.calibrationcurves(
  proportion = 0.5,
  cc1 = "IntCal13.14C",
  cc2 = "Marine13.14C",
  name = "mixed.14C",
  dirname = ".",
  offset = c(0, 0),
  sep = "\t"
)

Arguments

proportion	Proportion of the first calibration curve required. e.g., change to proportion=0.7 if cc1 should contribute 70% (and cc2 30%) to the mixed curve.
cc1	The first calibration curve to be mixed. Defaults to the northern hemisphere terrestrial curve IntCal13.
cc2	The second calibration curve to be mixed. Defaults to the marine curve IntCal13.
name	Name of the new calibration curve.
dirname	Directory where the file will be written. If using the default dirname=".", the new curve will be saved in current working directory.
offset	Any offset and error to be applied to cc2 (default 0 +- 0).
sep	Separator between fields (tab by default, "\t")

Details

The proportional contribution of each of both calibration curves has to be set.

Value

A file containing the custom-made calibration curve, based on calibration curves cc1 and cc2.
