centreOfMass

A data frame of class <code>vectors</code>

object


The $x$ coordinate of the centre of mass is defined as $\frac{\sum(m_ix_i)}{\sum(m_i)}$ where $m_i$ is the biomass of the $i^{th}$ branch and $x_i$ is the $x$ coordinate of the $i^{th}$ branch. $y$ and $z$ coordinates are similarly computed.
The centre of mass computation excludes branches to be pruned (ie: those whose <code>toBePruned</code> value is set to <code>TRUE</code>).


The centre of mass is a crucial data for arborists in order to
consolidate a tree using steel or dynamic cables. Given field-recorded data
on branchiness of a tree, the package: (i) computes and plots the centre of
mass of the tree itself, (ii) computes branches slenderness coefficient in
order to aid the arborist identify potentially dangerous branches, and
(iii) computes the force acting on a ground plinth and its best position
relating to the tree centre of mass, should the tree need to be stabilized
by a steel cable.
