#' Legendre and Gallagher Synthetic Example
#' 
#' A data set used as a synthetic example in paper Legendre and Gallagher
#' (2001).
#' 
#' @docType data
#' 
#' @name LGDat
#' 
#' @usage data(LGDat)
#' 
#' @format A 19 rows by 10 columns \code{\link{data.frame}}.
#' 
#' @details This synthetic data set is described by Legendre and Gallagher
#' (2001) and was used to test species abundance transformations. Its first
#' column contains geographic locations from 1 to 19 (no particular units are
#' specified). The five columns that follow contain abundances of five species
#' with abundances peaking at 7-8 at different locations (site 1, 5, 10, 15, and
#' 19). The latter are considered "abundant species". For next four columns
#' contains abundances of "rare species" occurring in between the abundance
#' species (abundances from 1 to 4).
