Delete edges from a graph

## Usage

delete_edges(graph, edges)

## Arguments

graph

The input graph.

edges

The edges to remove, specified as an edge sequence. Typically this is either a numeric vector containing edge IDs, or a character vector containing the IDs or names of the source and target vertices, separated by |

## Value

The graph, with the edges removed.

## Examples

g <- make_ring(10) %>%
delete_edges(seq(1, 9, by = 2))
g
#> IGRAPH 4d869ad U--- 10 5 -- Ring graph
#> + attr: name (g/c), mutual (g/l), circular (g/l)
#> [1] 2-- 3 4-- 5 6-- 7 8-- 9 1--10

g <- make_ring(10) %>%
delete_edges("10|1")
g
#> IGRAPH 04a247d U--- 10 9 -- Ring graph
#> + attr: name (g/c), mutual (g/l), circular (g/l)
#> + edges from 04a247d:
#> [1] 1-- 2 2-- 3 3-- 4 4-- 5 5-- 6 6-- 7 7-- 8 8-- 9 9--10

g <- make_ring(5)
g <- delete_edges(g, get.edge.ids(g, c(1, 5, 4, 5)))
g
#> IGRAPH f6b15a4 U--- 5 3 -- Ring graph
#> + attr: name (g/c), mutual (g/l), circular (g/l)
#> + edges from f6b15a4:
#> [1] 1--2 2--3 3--4
