Computes 3 distance matrices accounting for the (i) turnover (replacement), (ii) nestedness-resultant component, and (iii) total dissimilarity (i.e. the sum of both components).
beta.pair(x, index.family = "sorensen")
The function returns a list with three dissimilarity matrices.
For index.family="sorensen"
the three matrices are:
dist
object, dissimilarity matrix accounting for spatial turnover (replacement), measured as Simpson pair-wise dissimilarity
dist
object, dissimilarity matrix accounting for nestedness-resultant dissimilarity, measured as the nestedness-fraction of Sorensen pair-wise dissimilarity
dist
object, dissimilarity matrix accounting for total dissimilarity, measured as Sorensen pair-wise dissimilarity (a monotonic transformation of beta diversity)
For index.family="jaccard"
the three matrices are:
dist
dissimilarity matrix accounting for spatial turnover, measured as the turnover-fraction of Jaccard pair-wise dissimilarity
dist
object, dissimilarity matrix accounting for nestedness-resultant dissimilarity, measured as the nestedness-fraction of Jaccard pair-wise dissimilarity
dist
object, dissimilarity matrix accounting for beta diversity, measured as Jaccard pair-wise dissimilarity (a monotonic transformation of beta diversity)
data frame, where rows are sites and columns are species. Alternatively x
can be a betapart
object derived from the betapart.core
function
family of dissimilarity indices, partial match of "sorensen"
or "jaccard"
