how to convert list of “vertex sequence” to a vector

Question

I am using Igraph package in R and when I am accessing the list of vertices names through V(graph), I am getting the following result:

Vertex sequence:
 [1]          


        

Answer 1

.... Ok, I found a way out:

V(graph)$name will give me a vector of names

Answer 2

For a more general case, just use the as_ids() function.
