getDoubleBark: get double bark thickness inside tree taper

In frumentum/rBDATPRO: Imports functions of windows programm BDAT in R

Description

This function calculates bark's double thickness of a given diameter inside for a given tree of dimensions (dbh, h).

Usage

getDoubleBark(sp, d, h, hx, H1 = 1.3, D2 = 0, H2 = 0)

Arguments

sp	species code from BDAT
d	diameter in breast height (dbh) of tree
h	height of tree
hx	height for which diameter is required
H1	height where d was measured; default is 1.3[m] for dbh
D2	diameter at second height H2; if D2 = 0 (default) taper form from the first NFI ('Bundeswaldinventur I') is used
H2	according to D2, default is 0

Details

Strictly speaking getH is a wrapper function. It loads the fortran subroutine BDATHXDX within a call of loadBDAT.

Value

height of diameter dx

Examples

getDoubleBark(sp=1, d=30, h=40, hx=20)
