rdh_theory: Calculate metric based on geometric plane equation

Description

Calculates either rugosity, fractal dimension or height range based on the other two variables.

Usage

rdh_theory(R, D, H, L, L0)

Value

A value corresponding one of the three variables not given to the function.

Arguments

R, D, H

Two of the three variables to calculate the third.

L

Extent.

L0

Resolution.

Details

This function uses the geometric plane equation from Torres-Pulliza et al. (2020) to calculate one of rugosity, fractal dimension or height range based on the other two variables.
