In UCL/ADMUR: Ancient Demographic Modelling Using Radiocarbon

Quick calibration of dates, without the need to choose a date range or generate a CalArray

Description

Wrapper function that easily generates and plots an SPD, at the cost of some user control

Usage

summedCalibratorWrapper(data, calcurve = intcal20, plot = TRUE)

Arguments

data	A dataframe of 14C dates. Requires 'age' and 'sd'.
calcurve	A calibration curve object. Choose from intcal20 (default), shcal20, intcal13 or shcal13.
plot	By default (TRUE) will plot the SPD.

Details

Function to easily plot a calibrated Summed Probability Distribution from 14C dates. Automatically chooses a sensible date range and interpolation increments. Uses these to generate CalArray internally.

Value

Returns a single-column data frame of SPD probabilities. Row names are the calendar years.

Examples

	# SPD of two 14C dates, calibrated through intcal20 (default)
	data <- data.frame(
		age=c(6562,7144),
		sd=c(44,51)
		)
	x <- summedCalibratorWrapper(data)

	# one date is not 14C
	data <- data.frame(
		age = c(6562,7144),
		sd = c(44,51),
		datingType = c('14C','TL')
		)
	x <- summedCalibratorWrapper(data)
