How to select edge randomly from graph in R?


I have a regular graph and wanna delete randomly edge from graph. How to select edges randomly till I can delete?

library(igraph)
g = sample_k_regular(10,3)

Solution

  • You can use the sample(x,n) function in base R along with delete_edges from igraph.

    For example, if you want to delete 5 edges:

    library(igraph)
    g = sample_k_regular(10,3)
    g1 <- delete_edges(g,sample(E(g),5)) 
    

    E(g) gets a list of edges that sample randomly samples from.
