Description Usage Arguments Value Source

Description

Compute sorting coefficient from cumulative distribution data

Usage

1
stat.sorting(sieve_size, cumu, units = "phi", method = "all")

Arguments

sieve_size

vector of sieve sizes related to input cumulative distribution

cumu

cumulative distribution pertaining to sieve sizes

units

sieve size units "phi" = phi scale, "mm" = milimeter (metric) scale

method

Method to calculate sorting coefficient. Only algebraic methods available. "inm" = Inman, 1952. Algebraic method using central values; "fw" = Folk and Ward, 1957. Algebraic method to account for tail values. "all" = dataframe output with above calculations.

Value

a value or dataframe containing specified sorting coefficients.
