Description

Calculate equifinal dates for each point in the calibration curve

Usage

1

Arguments

calibDf

The calibration data frame, with columns yearBP, uncalYearBP, and uncalYearBPError

Details

The input calibration data frame has three columns: yearBP, uncalYearBP, and uncalYearBPError. For each date in the column yearBP, determine all other dates with the same fraction modern. These dates are equifinal since, in the absence of additional information, there is no way to determine which year a sample came from. Typically the actual equifinal date lies between two observations in yearBP, so linear interpolation is used to estimate the decimal year. A list of length nrow(calibDf) is returned with, for each point in the calibration curve, the following information:

indBase – The row index in calibDf of the point yBase – The calendar date (AD) of the point indEqui – The row index/indices in calibDf of the equifinal points yEqui – The calendar date(s) (AD) of the equifinal points

Value

A list of equifinality information for each point in the calibration curve (see details)
