Climate change – scurrilous rag.

This R-based project aims to make insect outbreak histories producible using tree-ring data. While still in its early stages (v. 0.2), it currently allows for fast outbreak history reconstructions using outputs from the popular dplR package. All that’s needed is tree-level host data and a nonhost chronology. Sample data are available through Dropbox.

If you have any feedback on this version or you’re a researcher who wants to try these methods, please check my contact information at the end!

Preparing dendrochronological datasets in R

In 2017 and 2018, I worked in a forestry research laboratory in Washington State. While I worked primarily with R and specialty software like CDendro, the managers I worked with had little-to-no familiarity with my methods. I wrote this report for them as a means to explain my methods in R and create a pipeline that can be reused across every dendrochronological dataset. I’m sharing this here as a means to preserve that pipeline for future analyses.
