#' @title MMR-derived root length data for SDEF root analysis.
#'
#' @description
#'
#' Each row is a single root.
#'
#' \code{'plot'} describes the plot that the data came from - in this dataset, either
#' 'adenostoma' or 'grass'.
#'
#' \code{'veg_type'} is the functional type of the plot, either "shrub" or "grass".
#'
#' \code{'tube'} is the tube replicate ID, 1-3 from 'adenostoma' and 4-6 from 'grass'
#'
#' \code{'frame'} is the viewing frame - 1 is closest to surface. Tiles are 8.4mm height,
#' 6.3mm wide, and have a variable depth that is not currently standardized within the
#' literature.
#'
#' \code{'root'} is root number within a particular tile.
#'
#' \code{'date'} records the date that the root was measured.
#'
#' \code{'length'} is the length of the root measured, in millimeters.
#'
#' \code{'diameter'} is the diameter of the root measured, in millimeters.
