Analysis of Ecological Data: Exploratory and Euclidean Methods in Environmental Sciences (ade4)

Presentation

ade4 is a software developed in the Biometry and Evolutionary Biology Lab (UMR 5558) - University Lyon 1 for the Data Analysis of Ecological and Environmental data in the framework of Euclidean Exploratory methods, hence the name ade4.

ade4 is a package for the R software since 2002. It contains functions for exploratory multivariate data analysis and graphical display, many numerical data sets and bibliographic references. Simple one-table methods are described in Chessel et al. (2004). Two-table and K-table methods are described in Dray et al. (2007). The theory of the duality diagram and its implementation in ade4 are discussed in Dray et Dufour (2007).

A book in the Springer Series in Statistics collection, "Multivariate Analysis of Ecological Data with ade4" presents the package. The examples and the graphs in this book can be reproduced online here.

## Getting started with **ade4** ### Installing **ade4** [This page](http://adeverse.github.io/ade4/articles/install.html) explains how to install the **ade4** package in **R**. ### Vignettes Several vignettes are available to help you get started with **ade4** (more to come soon !): - [Graphical representation of multivariate data](https://cran.r-project.org/web/packages/adegraphics/vignettes/adegraphics.html) - [Description of environmental variables structures](http://adeverse.github.io/ade4/articles/ChapEnvVarStruct.html) - [Description of species structures](http://adeverse.github.io/ade4/articles/ChapSpeciesStruct.html) - [Taking into account groups of sites](http://adeverse.github.io/ade4/articles/ChapBetGr.html) - [Description of species-environment relationships](http://adeverse.github.io/ade4/articles/Chap2tables.html) - [Analysing Changes in Structures](http://adeverse.github.io/ade4/articles/ChapKtables.html) - [Analysing Changes in Co-structures](http://adeverse.github.io/ade4/articles/Chap2Ktables.html) ### List of function references You can also find a list of functions available to users on the [reference page](http://adeverse.github.io/ade4/reference/index.html). ### Other resources Check out the [ade4 book](http://adeverse.github.io/ade4/articles/book.html) and its [shiny application](https://lbbe-shiny.univ-lyon1.fr/Reproducible_Research/Book/) for a complete introduction to the package and to rerun the code present in the book. You can also check these [bibliographic references](http://adeverse.github.io/ade4/articles/papers.html) to help you understand **ade4** methods. Note for nostalgics 😉 : the **old ade4 web site** is still available here: [http://pbil.univ-lyon1.fr/ADE-4/](http://pbil.univ-lyon1.fr/ADE-4/accueil2.php). ### Using **ade4** online: the Shiny app Consider giving a try to our shiny app, developed to allow you to run an analysis without having to write your own script: [ade4shiny](https://lbbe-shiny.univ-lyon1.fr/ade4shiny/). You will be able to download the R script used to generate the results as well as the analyses outputs and graphical representations. ### Getting help: FAQ & Mailing list You can also check the [FAQ section](http://adeverse.github.io/ade4/articles/faq.html) to check if your question has already been answered or ask for help on the **ade4** mailing list [adelist](https://listes.univ-lyon1.fr/sympa/info/adelist). \
