getFinalSegmentVolumeFunction: Function to estimate the volume of a final segment

In mbask/RBSperformance: An R package to aid in RBS estimations

Description

The terminal segment is usually the final leg of a branch, its volume may be estimated using its starting cross-section area and its length, times a form coefficient. The volume may be a target variable for RBS. This function computes what can be considered as the actual or true volume of a final segment of a tree. The actual volume would then be used to assess the precision of RBS estimators

Usage

  getFinalSegmentVolumeFunction(formCoefficient = "Apollonius")

Arguments

formCoefficient

a string linked to the actual form coefficient to be used. It may take the following values: "SolidCylinder" (value = 1), "Apollonius" (default, value = 0.6), "Cubic" (value = 0.5), "SolidCone" (value = 0.33), and "Neiloid" (value = 0.25).

Value

a function to be used to compute the volume of the terminal segment

Note

This is a container function for a closure, whose parameters are 'area', the cross-section area of the segment, and 'length' the segment length.

Care must be taken to provide a common base unit of measure to 'area' and 'length' (eg. m2 and m, but not cm2 and m)

Examples

getFinalSegmentVolume <- getFinalSegmentVolumeFunction()
getFinalSegmentVolume(area = pi*5^2, length = 7*100)
