R Question

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)

Answer

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.
