AGB.ind: Above ground biomass (agb) based on one of the Chave...

In forestgeo/ctfs: Tools for the Analysis of Forest Dynamics

Description

Compute biomass (agb) based on one of the Chave (Oecologia, 2005) models for tropical forest types.

Usage

AGB.ind(df, dbhunit = "mm", plot = "bci", wsgdata = wsg.ctfs2,
  forest = "moist", ht.param = NULL, htmodel = predht.asym)

Arguments

df	A table with dbh and species names
dbhunit	'cm' or 'mm', only used for basal area
plot	Character string giving the name of the plot where the data comes from (as it appears in the names of the R Analytical Tables).
wsgdata	A wood-density table, see density_ind() and wsgdata_dummy.
forest	A forest type (for most lowland tropical plots, the default "moist" is recommended.)
ht.param	Height parameters to calculate height from diameter for every tree, using the Chave model with height passed to htmodel. If NULL (defauld) AGB.ind() uses Chave equations without height.
htmodel	Height model to use with a non-NULL ht.param.

Value

A vector of biomass in kg for every individual in the submitted table df.
