biomassCalculation: Calculate above ground biomass for Canadian tree species

In PredictiveEcology/pemisc: Miscellaneous Utilities Developed by the Predictive Ecology Group

Calculate above ground biomass for Canadian tree species

Description

Based on DBH or DBH and Height.

Usage

biomassCalculation(species, DBH, includeHeight, height, equationSource)

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

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

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

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

Arguments

species	Character string giving the species name.
DBH	Numeric. The tree's diameter at breast height (DBH, cm).
includeHeight	Logical. Whether the biomass is calculated based on DBH and height. If TRUE, height must be provided. Default FALSE.
height	Numeric. The tree's height (m).
equationSource	Character. Determine the sources of equations. Currently, this function 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 and taking the equations from Lambert 2005
 biomass1 <- biomassCalculation(species = species, DBH = DBH)

 # with height information and and taking the equations from Lambert 2005
 biomass2 <- biomassCalculation(species = species, DBH = DBH,
                                includeHeight = TRUE, height = height)
