cal() constructs a generic representation of a calibrated radiocarbon date
or other calendar-based probability distribution.
data.frame with two columns, with calendar years and associated probabilities.
character. Calendar system used. Default:
character. Lab code or other label for the calibrated sample.
integer. Uncalibrated conventional radiocarbon age (CRA) of the sample.
integer. Error associated with the uncalibrated sample.
character. Atmospheric curve used for calibration, e.g. "intcal20".
integer. Marine reservoir offset used in the calibration, if any.
integer. Error associated with the marine reservoir offset.
integer vector of length 2. The range of years over which the calibration was performed, i.e.
logical. Whether the calibration was calculated using F14C values instead of the CRA.
logical. Whether the calibrated probability densities were normalised.
numeric. Lower threshold beyond which probability densities were considered zero.
(Optional) Arguments based to other functions.
cal object: a data frame with two columns,
the calibrated probability distribution. All other values are stored as
