Relationship between species and groups of sites 
Introduction
Package indicspecies provides functions to conduct:
-
Indicator species analysis: Assess the strength and statistical significance of the relationship between species occurrence/abundance and groups of sites (De Cáceres & Legendre 2009; De Cáceres et al. 2010; De Cáceres et al. 2012).
-
Species niche analysis: Measure species niche metrics using resource categories (De Cáceres et al. 2011).
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:
1remotes::install_github("emf-creaf/indicspecies")
Additionally, users can have help to run package functions directly as package vignettes, by forcing their inclusion in installation:
1remotes::install_github("emf-creaf/indicspecies",
2 build_opts = c("--no-resave-data", "--no-manual"),
3 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).
Maintenance
Although not in active development, the R package is maintained by the Ecosystem Modelling Facility unit at CREAF (in Spain).
