## Usage

min_ratio(m = runif(20))

## Arguments

- m
- a vector of non-negative trait measures, one for each species

## Value

Returns the minimum size ratio difference between adjacent, ordered values.

## Description

Function to calculate the minimum size ratio (larger/next larger)
between species within an assemblage.

## Details

This index is based on the minimum size ratio (larger/next larger) difference between
consecutively ordered species in an assemblage. It is appropriate for
morphological traits, but not phenological ones.
