ROBIN (ROBustness In Network) is an R package for the validation of community detection. It has a double aim: it studies the robustness of a community detection algorithm and it compares the robustness of two community detection algorithms.

The package implements a methodology that detects if the community structure found by a detection algorithm is statistically significant or is a result of chance, merely due to edge positions in the network.

The package:

Examine the robustness of a community detection algorithm against random perturbations of the original graph
Tests the statistical difference between the stability measure curves created
Makes a comparison between different community detection algorithms to choose the one that better fits the network of interest
Gives a graphical interactive representation

Example 1: “Robustness of a community detection algorithm”

my_network <- system.file("example/football.gml", package="robin")
graph <- prepGraph(file=my_network, file.format="gml")
graphRandom <- random(graph=graph)
proc <- robinRobust(graph=graph, graphRandom=graphRandom, method="louvain")               
plot(proc)

#For the testing:
robinFDATest(proc)
robinGPTest(proc)

Example 2: “Comparison of two community detection algorithms”

my_network <- system.file("example/football.gml", package="robin")
graph <- prepGraph(file=my_network, file.format="gml")
comp <- robinCompare(graph=graph, method1="fastGreedy", method2="louvain")                
plot(comp)

In this example, the Louvain algorithm fits better the network of interest, as the curve of the stability measure varies less than the one obtained by the Fast greedy method. Lower the curve more stable is the community detection method.

#For the testing:
robinFDATest(comp)
robinGPTest(comp)
