Either a vector of calibrated ages (when |

he calibration curve to use. Only a single calibration curve is currently supported |
type |
Either 'ages' which uncalibrates a calibrated age values without error (i.e. just a lookup on the calibration curve), or a 'samples' which estimates both an uncalibrated mean age and a standard deviation |
pathToCalCurves |
The path to the calibration curve directory. Defaults to the location of the standard calibration curves given in the package |
