SimilarityMult: Etimation of multiple-community similarity measure

In JohnsonHsieh/SpadeR: Species Prediction and Diversity Estimation with R

Description

SimilarityMult This part computes the generalized Sorensen, Horn similarity, and Morisita similarity/dissimilarity indices for comparing frequency or abundance data from more than two communities.

Usage

SimilarityMult(X, q = 2, nboot = 200)

Arguments

X	a matrix of species sample frequencies (for abundance data), row is species number, and column is community number.
q	For q=0, the SpadeR computes the estimates of Sorensen index for paired-wise communities. For q=1, the SpadeR computes the estimates of 1-Horn index for paired-wise communities. For q=2, the SpadeR computes the estimates of Morisita index for paired-wise communities.
nboot	the number of bootstrap resampling times, default is 200.

Value

include every community data summary, overlap measure in all communities, and pair-wise similarity measure depended on which order you choose in two communities.
