centreOfMassModulus: Computes the modulus of the CM vector

In treecm: Centre of Mass Assessment and Consolidation of Trees

Description

The Centre of Mass vector starts from the tree base and points towards the CM. Its modulus is the distance between the CM (x, y, z) and tree base (0, 0, 0).

Usage

centreOfMassModulus(object)

Arguments

object

an object of CM class

Value

a real number

Note

This function is mainly needed to compute the moment of the tree. The CM modulus is the tree moment arm.

Examples

library(treecm)
data(stonePine1TreeData)
vectors <- treeVectors(stonePine1TreeData)
CM <- centreOfMass(object=vectors)
print(centreOfMassModulus(CM))
treeMoment <- buildTreeMomentObject(
 centreOfMassModulus(CM)
 , treeTotalBiomass(stonePine1TreeData)
 , centreOfMassAngle(CM)
 )
