Convert a foreign object to a cal_dist object

as_cal_dist() converts objects from other packages that represent calibrated radiocarbon distributions to the c14 cal_dist class. Methods are currently implemented for:

• CalDates: from rcarbon::calibrate()

• oxcAARCalibratedDate and oxcAARCalibratedDatesList: from oxcAAR::oxcalCalibrate()

• BchronCalibratedDates: from Bchron::BchronCalibrate()

These functions are intended for complex S3 objects from other packages. The generic constructor cal_dist() can be used for data frames and other base structures.

Usage

as_cal_dist(x, ...)

# S3 method for class 'data.frame'
as_cal_dist(x, ...)

# S3 method for class 'matrix'
as_cal_dist(x, ...)

# S3 method for class 'CalDates'
as_cal_dist(x, ...)

# S3 method for class 'oxcAARCalibratedDatesList'
as_cal_dist(x, ...)

# S3 method for class 'oxcAARCalibratedDate'
as_cal_dist(x, ..., which = c("prior", "posterior"))

# S3 method for class 'BchronCalibratedDates'
as_cal_dist(x, ...)

Arguments

x

Object from another package to be converted to a cal_dist object.

...

Unused

which

Which probability distribution to extract from an oxcAARCalibratedDate: "prior" (default) uses raw calibrated probabilities. "posterior" uses Bayesian posterior probabilities (error if not available).

Value

Vector of class c14_cal_dist (cal_dist).
