Package: SyncER 1.0.0

SyncER: Synchronicity Testing for Event Records

Evaluation of synchronous deposition across different event records using a log-ratio approach, and syncing age-depth models based on the availability of isochrons. Following the methodology of Wils & Ramisch (2026) <doi:10.1038/s41598-026-67943-7>. The synthetic example dataset used in the examples, tests and vignette is distributed separately in the companion data package 'SyncERdata'.
