eff_num_func_d_onerow

Description

eff_num_func_d_onerow

Usage

eff_num_func_d_onerow(arow_freq, D, tau, q)

Arguments

arow_freq

One replicate sample of different functions (a single numeric vector)

D

A distance matrix describing dissimilarity between functions.

tau

A cutoff for degree of dissimilarity under which functions are considered to be different. If tau is the minimum non-zero value of D, all functions are different. if tau is the maximum value of D are greater, all functions are considered the same.

q

Order of hill number used for index. Defaults to q=1, as in Shannon Diversity

Value

A single value of effective number of functions
