Ordination methods, diversity analysis and other
  functions for community and vegetation ecologists.

Static and dynamic 3D plots to be used with ordination
    results and in diversity analysis, especially with the vegan package.

'Vega' and 'Vega-Lite' parse text in 'JSON' notation to render 
  chart-specifications into 'HTML'. This package is used to facilitate the 
  rendering. It also provides a means to interact with signals, events,
  and datasets in a 'Vega' chart using 'JavaScript' or 'Shiny'.

A set of functions to: (1) perform fuzzy clustering of vegetation data (De Caceres et al, 2010) <doi:10.1111/j.1654-1103.2010.01211.x>; (2) to assess ecological community similarity on the basis of structure and composition (De Caceres et al, 2013) <doi:10.1111/2041-210X.12116>.

Handling of vegetation data from different sources (
	Turboveg 2.0 <https://www.synbiosys.alterra.nl/turboveg/>; 
	the German national repository <https://www.vegetweb.de> and others. 
    Taxonomic harmonization (given appropriate taxonomic lists,
    e.g. the German taxonomic standard list "GermanSL", <https://germansl.infinitenature.org>).

Collection of common methods to determine growing season length in
  a simple manner. Start and end dates of the vegetation periods are calculated
  solely based on daily mean temperatures and the day of the year.

Import and handling data from vegetation-plot databases, especially
    data stored in 'Turboveg 2' (<https://www.synbiosys.alterra.nl/turboveg/>).
    Also import/export routines for exchange of data with 'Juice'
    (<https://www.sci.muni.cz/botany/juice/>) are implemented.

Elaboration of vehicular emissions inventories,
    consisting in four stages, pre-processing activity data, preparing 
    emissions factors, estimating the emissions and post-processing of emissions 
    in maps and databases. More details in Ibarra-Espinosa et al (2018) <doi:10.5194/gmd-11-2209-2018>.
    Before using VEIN you need to know the vehicular composition of your study area, in other words,
    the combination of of type of vehicles, size and fuel of the fleet. Then, it is recommended to
    start with the project to download a template to create a structure of directories and scripts.
