as_cal() converts objects from other packages that represent calibrated
radiocarbon dates to cal objects.
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.
See cal() for a more generic constructor, e.g. using a data frame.
as_cal(x) # S3 method for CalDates as_cal(x) # S3 method for oxcAARCalibratedDatesList as_cal(x) # S3 method for oxcAARCalibratedDate as_cal(x) # S3 method for BchronCalibratedDates as_cal(x)
| x | object to be converted to a |

cal object: a data frame with two columns, year and p, representing
the calibrated probability distribution. All other values are stored as
attributes and can be accessed with cal_metadata().
Other functions for working with cal objects:
as.CalDates.cal(),
cal_metadata(),
cal()
