mix.curves {rplum} | R Documentation |
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.
mix.curves( proportion = 0.5, cc1 = "3Col_intcal20.14C", cc2 = "3Col_marine20.14C", name = "mixed.14C", dirname = ".", offset = c(0, 0), sep = "\t" )
proportion |
Proportion of the first calibration curve required. e.g., change to |
cc1 |
The first calibration curve to be mixed. Defaults to the northern hemisphere terrestrial curve IntCal20. |
cc2 |
The second calibration curve to be mixed. Defaults to the marine curve IntCal20. |
name |
Name of the new calibration curve. |
dirname |
Directory where the file will be written. If using the default |
offset |
Any offset and error to be applied to |
sep |
Separator between fields (tab by default, "\t") |
The proportional contribution of each of both calibration curves has to be set.
A file containing the custom-made calibration curve, based on calibration curves cc1
and cc2
.
