get_abc: Compute turnover components.

In valentinitnelav/bootdissim: Bootstrap Network Dissimilarity

Compute turnover components.

Description

Compute the a, b, c turnover components. Given two vectors, v1 and v2, of species names or interactions, component "a" is the number of elements (species or interactions) present in both vectors v1 and v2, "b" is the number of elements present only in v1 and "c" only in v2. See the section "Beta diversity estimates" in Novotny, V. (2009). Beta diversity of plant–insect food webs in tropical forests: a conceptual framework. Insect Conservation and Diversity, 2(1), 5-9.

Usage

get_abc(vect)

Arguments

vect	A list of two vectors with species names or interactions.

Value

A list with the 3 components a, b, c. The elements of the list are numeric vectors of length 1.

Examples

library(bootdissim)
library(bipartite)

net1 <- reshape_net(vazarr, seed = 1)
net2 <- reshape_net(vazcer, seed = 1)
vect <- get_interactions(net1, net2)
abc <- get_abc(vect)
