Description

this function is to calculate aboveground biomass for boreal species based on DBH or DBH and Height

Usage

biomassCalculation(species, DBH, heightIncluded, height, paperSource)


  ## S4 method for signature 'character,numeric,logical,numeric,character'
biomassCalculation(species,
  DBH, heightIncluded, height, paperSource)


  ## S4 method for signature 'character,numeric,missing,numeric,character'
biomassCalculation(species,
  DBH, height, paperSource)


  ## S4 method for signature 'character,numeric,logical,numeric,missing'
biomassCalculation(species,
  DBH, heightIncluded, height)


  ## S4 method for signature 'character,numeric,missing,numeric,missing'
biomassCalculation(species,
  DBH, height)


  ## S4 method for signature 'character,numeric,missing,missing,character'
biomassCalculation(species,
  DBH, paperSource)


  ## S4 method for signature 'character,numeric,missing,missing,missing'
biomassCalculation(species,
  DBH)

Arguments

species	Character string. The species name.
DBH	Numeric. The tree's diameter at breast height (DBH, cm).
heightIncluded	Logical. Whether the biomass is calculated based on DBH and height. If TURE, height must be provided. Default FALSE
height	Numeric. The tree's height (m).
paperSource	Character. Determine the sources of equations. Currently, this functions has two options, i.e., "Lambert2005" and "Ung2008". Default Lambert2005

Value

Biomass (kg) and missedSpecies list that was not calculated.

Examples

## Not run: 
 DBH <- seq(1, 100, 5)
 species <- c(rep("jack pine", 10), rep("black spruce", 10))
 species[1] <- "wrongSpecies"
 height <- seq(20, 40, length = 20)
 # without height information and taking the eqations from Lambert 2005
 biomass1 <- biomassCalculation(species = species, DBH = DBH)
 # with height information and taking the eqations from Lambert 2005
 biomass2 <- biomassCalculation(species = species, DBH = DBH,
                                heightIncluded = TRUE, height = height)

## End(Not run)
