treeSR: Computes slenderness ratio for tree branches

Description Usage Arguments Value Note References See Also

View source: R/SC.R

Description

slenderness ratio is an important index of stability of trees and branches

Usage

1
treeSR(treeObject, vectorObject)

Arguments

treeObject

an object of treeData class

vectorObject

an object of vectors class

Value

an object of class SR

Note

The coefficient takes into account branch angle: SL_c=\frac{L}{D} \cdot (1 + cos(a)), where a is the branch angle (0 degrees = horizontal, 90 degrees vertical). Vertical branches have SL = SL_c
