Reorient a graph vector

nodes() and edges() return the same underlying graph, enumerated along the node or edge axis respectively, regardless of which orientation x started in. Both directions are lossless and involutive: node attributes, isolated nodes, and directed all survive, because both orientations carry the same logical graph — reorientation only changes which table the result is indexed by.

Usage

Arguments

x

A node_vec or edge_vec.

...

Passed on to methods.

Value

nodes() returns a node_vec. edges() returns an edge_vec.

Examples

g <- node_vec(
  x = c("A", "B", "C"),
  from = c(1L, 2L),
  to = c(2L, 3L)
)
edges(g)
#> <edge_vec[2]>
#> [1] [A]->[B] [B]->[C]
nodes(edges(g))
#> <node_vec[3]>
#> [1] A B C
