BiodiversityR is an R package for statistical analysis of biodiversity and ecological communities, including species accumulation curves, diversity indices, Renyi profiles, GLMs for analysis of species abundance and presence-absence, distance matrices, Mantel tests, and cluster, constrained and unconstrained ordination analysis.
The package was initially built to provide a graphical user interface and different helper functions for the vegan community ecology package. As documented in a manual on biodiversity and community ecology analysis, available from this website and this link, most analysis pipelines require a community matrix (typically having sites as rows, species as columns and abundance values as cell values) and an environmental data set (typically providing numerical and categorical variables for the different sites) as inputs. After being launched on CRAN, new methods from vegan have been integrated in the package as documented in the ChangeLog file.
A major update of BiodiversityR involved the inclusion of different methods of ensemble suitability modelling, as described here. Most of the functions for ensemble suitability modelling were named with a ensemble.XXXX() naming template.
At the end of 2021, some methods to facilitate plotting results via ggplot were included in BiodiversityR. These methods are described in detail in this rpubs series, with some examples given below.
library(BiodiversityR) # also loads vegan
library(ggplot2)
library(ggforce)
library(concaveman)
library(ggrepel)
library(ggsci)
library(dplyr)
library(pvclust)The data in the examples are data that were used as case study in Data Analysis in Community and Landscape Ecology and also in the Tree Diversity Analysis manual.
Data set dune is a community data set, where variables (columns) typically correspond to different species and data represents abundance of each species. Species names were abbreviated to eight characters, with for example Agrostol representing Agrostis stolonifera.

One of the variables is Management, a categorical variable that describes different management categories, coded as BF (an abbreviation for biological farming), HF (hobby farming), NM (nature conservation management) and SF (standard farming).

For the examples, we use the constrained ordination method of redundancy analysis.
The ordiplot object is obtained from the result of via function rda. The ordination is done with a community data set that is transformed by the Hellinger method as recommended in this article.

This information is extracted from the ordination model and not the ordiplot, hence it is important to select the same axes via argument ‘choices’. The extracted information includes information on the percentage of explained variation. I suggest that you cross-check with the summary of the redundancy analysis, where information on proportion explained is given.

Function ordiellipse.long reproduces similar ellipses as vegan::ordiellipse.
It is necessary to re-plot the ordiplot. It is also necessary to give the name of the Management variable explicitly as this was not captured in the ordiellipse result.

Where the previous example examined patterns for a categorical explanatory variable, here we will explore patterns for the continuous variable A1, documenting the thickness of the A1 horizon.
The vegan package includes a method of adding a smooth surface to an ordination diagram. This method is implemented in function ordisurf.
Function ordisurfgrid.long extracts the data to be plotted with ggplot2

Function pvclust.long extracts the data both from the pvclust object and a ordicluster object.
plot1 <- ordiplot(Ordination.model1, choices=c(1,2), scaling='species')
cl.data1 <- ordicluster(plot1,
cluster=as.hclust(dune.pv$hclust))
With a similar methodology as available in ordicluster, higher clustering levels in the hierarchy can be removed via variable prune available from the results for nodes and branches.
