fractdim {SoilFDA}

Computation of Fractal Dimension

Description

The function computes the fractal dimension of particle size distribution based on soil mass

Usage

fractdim(Mass, Size, TM, dmax)

Arguments

Mass

Numerical vector containing the mass of each particle size class

Size

Numerical vector containing the average of each particle size class

TM

Numerical value containing the total mass of soil

dmax

Numerical value containing the average of maximum particle size class

Value

Fractal Dimension

Examples

data <- data.frame(Mass = c(15.1,28.9,11.3,14.6,7.9,22.2),
                   Size = c(0.053,0.1765,0.4,1.25,3.375,4.75))
TM <- 100
dmax <- 4.75
attach(data)
fractdim(Mass = Mass, Size = Size, TM = TM, dmax = dmax)
