weightedmean R Documentation
Calculate the weighted mean age
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)
weightedmean(ages,"MD2-")
