sample_coreseq {netUtils}

Generate random graphs with a given coreness sequence

Description

Similar to sample_degseq just with coreness

Usage

sample_coreseq(cores)

Arguments

cores

coreness sequence

Details

The code is an adaption of the python code from https://github.com/ktvank/Random-Graphs-with-Prescribed-K-Core-Sequences/

Value

igraph object of graph with the same coreness sequence as the input

Examples

library(igraph)
g1 <- make_graph("Zachary")
kcores1 <- coreness(g1)
g2 <- sample_coreseq(kcores1)
kcores2 <- coreness(g2)

#the sorted arrays are the same
all(sort(kcores1)==sort(kcores2))
