AGBChv14: Function to estimate individual biomass for forests using a...

Description

Function to estimate individual biomass using Chave et al. (2014) pantropical model (model 4). Height is estimated using Feldpausch et al. (2011) regional parameters with Weibull equation. The function adds columns to the dataset with the biomass information for all alive trees. This function needs a dataset with the following information: PlotViewID, PlotID, TreeID, CensusNo, Diameter (DBH1-DBH4), Wood density (WD) and Allometric RegionID.The function assumes that the diameter used is DBH4, unless other DBH is selected. See ForestPlots.net documentation for more information.

Usage

AGBChv14(xdataset, dbh = "D4", height.data = NULL, param.type = "Best")

Arguments

xdataset	a dataset for estimating biomass
dbh	a diameter (in mm).
height.data	Object returned by param.merge. If NULL (default), then regional height-diameter equations are used.
param.type	Local height diameter to use. One of Best (defualt), BioRF,lusterF ... NEED TO DECIDE WHICH OF THESE TO RETURN
