+Companion code to *Inferring species interactions using Granger causality and convergent cross mapping* by F. Barraquand, C. Picoche, M. Detto and F. Hartig. [http://arxiv.org/abs/1909.00731](http://arxiv.org/abs/1909.00731)
 
 Linear Granger causality and convergent cross-mapping are implemented using ``R``. Here, we stick to time-domain approaches from packages ``vars`` and ``lmtest`` for Granger causality, as well as [SIMoNe](http://julien.cremeriefamily.info/simone.html) for regularized models, and call ``rEDM`` for convergent cross-mapping (see Hao Ye et al.'s [tutorial](https://cran.r-project.org/web/packages/rEDM/vignettes/rEDM-tutorial.html) for more information).
