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:

Package installation

Package ecotraj can be found at CRAN. In addition, the latest stable ecotraj R package can also be installed from GitHub as follows:

remotes::install_github("emf-creaf/ecotraj")

Additionally, users can have help to run package functions directly as package vignettes, by forcing their inclusion in installation:

remotes::install_github("emf-creaf/ecotraj", 
                         build_opts = c("--no-resave-data", "--no-manual"),
                         build_vignettes = TRUE)
