Dbh: Extract pre-defined diameter

In TapeS: Tree Taper Curves and Sorting Based on 'TapeR'

Extract pre-defined diameter

Description

Function extracts pre-defined diameters, e.g. dbh (in 1.3m) or D03 (in 30% of tree height) for a tprTrees-object

Usage

Dbh(obj)

Bhd(obj)

D13(obj)

D7(obj)

D03(obj)

D005(obj)

Arguments

obj	a object of class 'tprTrees'

Details

a wrapper around tprDiameter to calculate specifically defined diameters like diameter in breast height (dbh), diameter in 7m above ground or in 5% and 30% of tree height.

Value

diameter(s) in predefined heights

Functions

• Dbh(): wrapper to calculate diameter in breast height

• Bhd(): German alias for function Dbh

• D13(): Height specific alias for function Dbh

• D7(): Function to calculate diameter over bark in 7m above ground

• D03(): Function to calculate diameter over bark in 30% of tree height

• D005(): Function to calculate diameter over bark in 5% of tree height

Examples

t <- tprTrees()
Dbh(t) # diameter in breast height (i.e. 1.3m)
Bhd(t) # same, german named function name
D13(t) # same, height related function name
D005(t) # diameter in 5% of tree height
D7(t) # diameter in height of 7m
D03(t) # diameter in 30% of tree height
