| poolDates {rcarbon} | R Documentation |
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)
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.
Value
A data.frame containing the weighted radiocarbon ages and errors for each event and the associated T-values and P-values.
