#' @title Vegetation-Plots Sampled in Four Syntaxa
#'
#' @description
#' Data set collected in several stands of vegetation belonging to four
#' phytosociological, namely Eleocharito-Caricetum bohemicae (class
#' Isoëto-Nanojuncetea), Gentiano-Koelerietum pyramidetae (class
#' Festuco-Brometea), Mesobrometum (class Festuco-Brometea), and
#' Alliario-Chaerophylletum temuli (class Galio-Urticetea).
#'
#' The data set is stored as a list, including four data frames: \code{Head}
#' whit plots information, \code{RelevesList} including the abundance of
#' species in single plots (as a column oriented table), \code{SpeciesList}
#' with the information of single species, and \code{CoverConversion} with the
#' conversion table for Braun-Blanquet abundance to percentage cover.
#'
#' This data set is offered as alternative for examples working with
#' Ellenberg's indicator values (EIV) and life forms. The analysis of those
#' data was published in (\bold{Alvarez et al. 2013}).
