Lagged Cross-Correlation Analysis of Environmental Time Series R package ecoXCorr version 0.2.1 Tools for analysing lagged relationships between environmental variables and ecological or epidemiological time series. The package implements a workflow to aggregate meteorological data over multiple lagged intervals, fit regression models, including mixed-effect models using 'glmmTMB', for each lag window, and visualise varied models outcomes (effect strength and direction, model prediction error...) using cross-correlation maps ('CCM'). Software Depends: R (>= 3.5) Imports: glmmTMB, ggplot2, stats, performance, Rdpack, shiny, scales Suggests: testthat (>= 3.0.0), readr Nicolas Moiroux <nicolas.moiroux@ird.fr> Comprehensive R Archive Network (CRAN) Nicolas Moiroux [aut, cre] (ORCID: <https://orcid.org/0000-0001-6755-6167>), Colombine Bartholomée [aut] (ORCID: <https://orcid.org/0000-0001-7291-5195>), Paul Taconet [aut] (ORCID: <https://orcid.org/0000-0001-7429-7204>) GPL (>= 3) 2026-04-01 application/tgz https://CRAN.R-project.org/package=ecoXCorr doi:10.32614/CRAN.package.ecoXCorr
