R: A Language and Environment for statistical computing

Abstract

This document describes basic features of dplR by following the initial steps that an analyst might follow when working with a new tree-ring data set. The vignette starts with reading in ring widths and plotting them. We describe a few of the available methods for detrending and then show how to extract basic descriptive statistics. We show how to build and plot a simple mean-value chronology. We also show how to build a chronology using the expressed population signal from the detrended ring widths as an example of how more complicated analysis can be done using dplR.
