Introduction
Package ecotraj
is a package providing Ecological Trajectory Analysis
(ETA), a framework to assist ecologists in the analysis of temporal
changes in ecosystems defined on a chosen multivariate space.
ETA is related to the following publications:
-
First presentation of the community trajectory analysis framework: De Cáceres et al. (2019) (https://doi.org/10.1002/ecm.1350).
-
Extension of community trajectory analysis: Sturbois et al. (2021) (https://doi.org/10.1016/j.ecolmodel.2020.109400).
-
Generalisation to stable isotope data: Sturbois et al. (2021) (https://doi.org/10.1002/ecm.1501).
-
Application of ETA for the assessement of ecological status: Sturbois et al. (2023).
Package installation and documentation
