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()
