Q_INFCvpe: Volume and Phytomass Estimates

In npuletti/ForITdev: Functions from the 2nd Italian Forest Inventory (INFC)

Description

The function estimates tree volume and phytomass per species from stem diameter at 1.3 m height (DBH) and total height (HT)

Usage

Q_INFCvpe(mydata)

Arguments

mydata

Value

Returns a list with the following objects:

$mainData

a data.frame with the following columns spg a string with the species group code d130 a value indicating the stem diameter at 1.3 m height (DBH) [cm] h_tot a value indicating the total stem height (HT) [m] freq the number of trees of the same spg with equal DBH and HT mod a character, the same as mod in arguments. T_0 a value of the estimates for mod value. v is expressed in dm^3 while dw1, dw2, dw3, dw4 are expressed in kg; SEE a value of Standard Error of the Estimates dof the degree of freedom in.range tree inside (y) or out of the range (n) of the sampled trees in Gasparini and Tabacchi (2011)

out.of.range

a data.frame listing the trees out of the range of application (domain)
