#' @title Anatomical measurements
#'
#' @description This example dataset includes ROXAS output files (cf. von Arx & Carrer, 2014) with lumen area and cell wall thickness measurements from;
#' i) Norway Spruce (\emph{Picea abies}) from the Loetschental, Switzerland (2007-2013),
#' ii) Siberian larch (\emph{Larix siberica}) from Siberia, Russia (2007-2010),
#' iii) Stone pine (\emph{Pinus cembra}) from the Dolomite mountains, Italy (2007-2010), and
#' iv) Scots pine (\emph{Pinus sylvestris}) from the eastern lowlands, Germany (2007-2010).
