distMS {adiv}

Marczewski-Steinhaus Coefficient

Description

The function calculates the Marczewski-Steinhaus coefficient of dissimilarity between pairs of entities (e.g. communities)

Usage

distMS(comm, diag = FALSE, upper = FALSE)

Arguments

comm

a data frame or a matrix of nonnegative values (e.g. abundance of species (columns) within communities (rows) to obtain dissimilarities between communities).

diag

a logical value indicating whether the diagonal of the distance matrix should be printed by function print.dist.

upper

a logical value indicating whether the upper triangle of the distance matrix should be printed by function print.dist.

Value

an object of class dist

Note

This function is a modification of function dist.quant from library ade4 where other dissimilarity coefficients can be found.
