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
