rcarbon (version 1.5.1)

poolDates: Combine radiocarbon ages from the same event.

Description

Computes a combined weighted mean and error and carries out a statistical test for internal consistency.

Usage

poolDates(x, errors, id = NULL, F14C = TRUE)

Value

A data.frame containing the weighted radiocarbon ages and errors for each event and the associated T-values and P-values.

Arguments

x

A vector of uncalibrated radiocarbon ages

errors

A vector of standard deviations corresponding to each estimated radiocarbon age

id

A vector of event/object identifiers to be matched with radiocarbon ages. If not supplied all radiocarbon ages are assumed to be from the same event/object.

F14C

Whether calculations are carried out in F14C space or not. Default is TRUE.

Details

The function calculates combined weighted error mean and standard error for each set of radiocarbon ages associated with the same event or object and computes a significance test for evaluating internal consistency following Ward and Wilson's method (1978). This is equivalent to OxCal's R_Combine routine.

Examples

Run this code
x = c(4300,4330,5600,5603,5620)
errors = c(20,30,30,30,45)
id = c(1,1,2,2,2)
poolDates(x,errors,id)
