Description Usage Arguments Value

View source: R/betalink.r

Description

measures the beta-diversity between two networks

Usage

1
betalink(n1, n2, bf = B01)

Arguments

n1

network 1 (as an igraph object)

n2

network 2 (as an igraph object)

bf

any function to measure beta-diversity between two sets

Value

a list with components S, OS, WN, and ST. While interpreting the output, it is important to consider that ST is strongly constrained by the values of S (the species composition dissimilarity). ST is only really meaningful when the values of S are "intermediate"; a good example is when the networks have been sampled along a gradient, and a more or less equal proportion of the species show turnover from one step to the next. In the situations where S is either really high or really low, the values of ST are constrained and should no be given importance. The values of OS and WN, and how they relate to S, have more informative value.
