Description: Offers tools for data formatting, anomaly detection, and classification
 of tree-ring data using spatial comparisons and cross-correlation. 
 Supports flexible detrending and climate–growth modeling via generalized
 additive mixed models (Wood 2017, ISBN:978-1498728331) and the 'mgcv'
 package (<https://CRAN.R-project.org/package=mgcv>), enabling robust
 analysis of non-linear trends and autocorrelated data. Provides
 standardized visual reporting, including summaries, diagnostics, and
 model performance. Compatible with '.rwl' files and tailored for the
 Canadian Forest Service Tree-Ring Data (CFS-TRenD) repository
 (Girardin et al. (2021) <doi:10.1139/er-2020-0099>), offering
 a comprehensive and adaptable framework for dendrochronologists working
 with large and complex datasets.
