#' Global Plants data
#'
#' Data inspired by a worldwide study of plant height and its association with climate and latitude (Moles \emph{et al.} 2009).
#' Height is recorded for one dominant plant at each of 178 sites, along with dozens of climatic variables extracted from BIOCLIM.
#' Sites, climate data and species lists come from Moles \emph{et al.} (2009) but height data are not actually field measurements,
#' due to data unavailability. Instead height has been taken from species descriptions available on Google, accessed 7/1/21.
