View source: R/BDATDORHX.R

Description

Function to call BDAT Fortran subroutine to calculate diameter under bark in height Hx for specified tree/s.

Usage

1
BDATDORHX(BDATArtNr, D1, H1, D2, H2, H, Hx)

Arguments

BDATArtNr

numeric vector of species code; see getSpeciesCode.

D1

first measured diameter of tree [cm], e.g. diameter in breast height

H1

measurement height of D1 [m]

D2

second measured diameter of tree, see buildTree for details on how to specify different taper forms

H2

measurement height of D2, see buildTree for details on how to specify different taper forms

H

total tree height [m]

Hx

height in tree for which diameter under bark is required

Details

conventional function interface for BDATDORHX. See getDiameter for more details.

Value

vector of diameters under bark

# same with variables

H <- 25
Hx <- 1.3
