Introduction

Package indicspecies provides functions to:

Package installation

Packageindicspecies can be found at CRAN package repository. In addition, the latest stable indicspecies R package can be installed from GitHub as follows:

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

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

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

Usage

Use strassoc() for assessing strength of associations and signassoc() to assess the statistical significance of the associations (De Cáceres & Legendre 2009). Much more complete functions are multipatt() (De Cáceres et al. 2010) and indicators() (De Cáceres et al. 2012).
