biomassCalculator
#' This function is to calculate aboveground biomass for boreal species based on DBH
#' or DBH/Height
#'
#' @param species Character string. The species name.
#'
#' @param DBH Numeric. The tree's diameter at breast height (DBH, cm).
#'
#' @param heightIncluded Logical. Whether the biomass is calculated based on DBH and height.
#' If TURE, height must be provided.
#' Default \code{TRUE}
#'
#' @param height Numeric. The tree's height (m).
#'
#' @param paperSource Character. Determine the sources of equations. Currently, this functions has two
#' options, i.e., "Lambert2005" and "Ung2008".
#' Default \code{Lambert2005}
#'
#' @return Biomass (kg) and missedSpecies list that was not calculated.

Defines functions biomassCalculator
Documented in biomassCalculator
#' This function is to calculate aboveground biomass for boreal species based on DBH
#' or DBH/Height
#'
#' @param species Character string. The species name.
#'
#' @param DBH Numeric. The tree's diameter at breast height (DBH, cm).
#'
#' @param heightIncluded Logical. Whether the biomass is calculated based on DBH and height.
#' If TURE, height must be provided.
#' Default \code{TRUE}
#'
#' @param height Numeric. The tree's height (m).
#'
#' @param paperSource Character. Determine the sources of equations. Currently, this functions has two
#' options, i.e., "Lambert2005" and "Ung2008".
#' Default \code{Lambert2005}
#'
#' @return Biomass (kg) and missedSpecies list that was not calculated.
