This is a generic function to convert R objects to igraph graphs.
Examples
## These are equivalent
graph_(cbind(1:5, 2:6), from_edgelist(directed = FALSE))
#> Warning: `graph_()` was deprecated in igraph 2.1.0.
#> ℹ Please use constructors directly, for instance graph_from_edgelist().
#> ℹ graph_() will be removed in a future version of igraph.
#> IGRAPH dec734a U--- 6 5 --
#> + edges from dec734a:
#> [1] 1--2 2--3 3--4 4--5 5--6
graph_(cbind(1:5, 2:6), from_edgelist(), directed = FALSE)
#> IGRAPH 3788a22 U--- 6 5 --
#> + edges from 3788a22:
