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

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.curves(
  proportion = 0.5,
  cc1 = "3Col_intcal13.14C",
  cc2 = "3Col_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")

Value

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

Details

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