ForIT-package: Volume and Biomass computations by Italian Forest Inventory

In npuletti/ForIT: Functions to estimate tree volume and phytomass in the Italian forest inventory 2005

Description

The ForIT package allows the computation of the biomass and volume functions carried out by Gasparini and Tabacchi (2011) and Tabacchi et al. (2011a) during the 2nd Italian National Forest Inventory. An English description of the methodology is provided by Tabacchi et al. (2011b). This package is intended as the translation in R of the literature cited above.

Examples

# one single tree
INFCvpe('Acca', 22, 14, mod='v', freq=2, aggr=FALSE)

# a list with ten trees of the same specie
INFCvpe(rep('Acca',10),d=c(10,15,20,30,32,24,36,40,8,18),
    h=c(7,9,12,20,21,18,21,22,8,12), mod='v', aggr=TRUE)

# a list of different species
species <- rep(c('Abal','Piab'),2)
dbh <- c(10,41,20,30)
heigths <- c(12,14,13,15)
frequences <- c(2,6,5,4)
data.frame(species, dbh, heigths, frequences)

# single-tree estimates
INFCvpe(species, dbh, heigths, mod='v', frequences, aggr=FALSE)

# estimates aggregated at species level
INFCvpe(species, dbh, heigths, mod='v', frequences, aggr=TRUE)
