Description

Function for generating a vector median calibrated dates from a CalDates class object.

Usage

1
2
mixCurves(calCurve = "intcal13", p = 1, resOffsets = 0,
  resErrors = 0)

Arguments

calCurve

Name of the terrestrial curve, either 'intcal13' or 'shcal13'. Default is 'intcal13'.

p

Proportion of terrestrial contribution. Deafult is 1.

resOffsets

Offset value for the marine reservoir effect. Default is 0.

resErrors

Error of the marine reservoir effect offset. Default is 0.

Details

The function is based on the mix.calibrationcurves function of the clam package.

Value

A three-column matrix containing calibrated year BP, uncalibrated age bp, and standard deviation. To be used as custom calibration curve for the calibrate function.
