However, applying this mathematical framework to empirical data is still challenging, precluding a larger adoption of the theoretical tools developed by empiricists. This package provides a complete toolbox for modelling interaction effects between species, and calculate fitness and niche differences. The functions are flexible, may accept covariates, and different fitting algorithms can be used. A full description of the underlying methods is available in GarcĂ­a-Callejas, D., Godoy, O., and Bartomeus, I. (2020) . Furthermore, the package provides a series of functions to calculate dynamics for stage-structured populations across sites.
