In ArArRedux: Rigorous Data Reduction and Error Propagation of Ar40 / Ar39 Data

Description

Computes the error weighted mean and MSWD of some samples taking into covariances.

Usage

weightedmean(ages, prefix = NULL)

Arguments

ages	an object of class results
prefix	is either a string with the prefix of the samples that need to be averaged, or a vector of sample names.

Value

a list with items:

avgt: the weighted mean age
err: the standard error of avgt
MSWD: the Mean Square of the Weighted Deviates

Examples

data(Melbourne)
ages <- process(Melbourne$X,Melbourne$irr,Melbourne$fract)
