The `c14_curve`

class represents a radiocarbon calibration curve, which
estimates the calendar ages corresponding to a set of radiocarbon
measurements. Usually calibration is performed with either one of the
standard curves included with the package (see c14_curves) or read in from
a file with `read_14c()`

.

`c14_curve()`

constructs a a new calibration curve using values in 14C years,
optionally with their associated d14C values.

`c14_fcurve()`

constructs a curve using fraction modern values (F14C or pMC),
typically used for "post-bomb" calibration.

## Arguments

- cal_age
Vector of calendar ages. If

`cal_age`

is an object of class era::yr, its epoch will be respected, otherwise it is assumed to be`"cal BP"`

.- c14_age
Vector of uncalibrated radiocarbon ages.

- c14_error
Vector of errors (sigma values) associated with

`c14_age`

.- d14c
Vector of Delta-14C values (optional).

- d14c_error
Vector of errors (sigma values) associated with

`d14c`

(optional).- f14c
Vector of fraction modern (F14C or pMC) values.

- f14c_error
Vector of errors (sigma values) associated with

`f14c`

.
