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

Description Usage Arguments Value Examples

Recursively concatenates a list of logratio data into one big dataset

1	concat(lrlist)

lrlist

a list containing items of class logratios or redux

an object of the same class as x containing the merged dataset
