calc_QSS_extinctions_seq: Calculates the QSS for an extinction sequence

In lsaravia/EcoNetwork: Ecological network analyses including multiplex networks

Calculates the QSS for an extinction sequence

Description

This functions calculates the QSS calc_QSS() for a sequence of incremental deletions of species (nodes) given by the vector seq, it does not produce secundary extinctions

Usage

calc_QSS_extinctions_seq(g_del, seq, nsim = 100, ncores = 0, istrength = FALSE)

Arguments

g_del	igraph object for the deletion sequence
seq	vector or list with the nodes for the extinction sequence, the extinctions are incremental.
nsim	number of simulations used in QSS calculation
ncores	number of cores used to calculate QSS
istrength	parameter istrength for QSS function

Value

data frame with the number of remaining nodes, the connectance, the number unconnected of components, the median QSS, and the name of the last deleted node. The first row are the values for the complete network.

Examples

## Not run: 
g <- netData[[1]]

# Generate random weights
#
V(g)$weight <-  runif(vcount(g))

# Without interaction strength
#
calc_QSS_extinctions_seq(g,V(g)$name[1:3],nsim=10,istrength = FALSE)

# With interaction strength
#
calc_QSS_extinctions_seq(g,V(g)$name[1:3],nsim=10,istrength = TRUE)

## End(Not run)
