Given a calendar age, the calibration curve (default cc=1) is interpolated and the corresponding F14C value and error are returned.

The cal BP year.
calibration curve for C14 (see caldist()).
Whether or not to use a postbomb curve (see caldist()).
How should R's approx function deal with extrapolation. If rule=1, the default, then NAs are returned for such points and if it is 2, the value at the closest data extreme is used.
Directory of the calibration curves. Defaults to where the package's files are stored (system.file), but can be set to, e.g., cc.dir="curves".
As an alternative to providing cc and/or postbomb, the data of a specific curve can be provided (3 columns: cal BP, C14 age, error).
Amount of decimals required for the F14C value. Defaults to 8.

Interpolation is used, and values outside the calibration curve are given as NA. For negative cal BP ages, a postbomb curve will have to be provided.
