An edge sequence.

incomparables

a vector of values that cannot be compared. Passed to base function duplicated. See details there.

Examples

g <- make_(ring(10), with_vertex_(name = LETTERS[1:10]))
E(g)[1, 1:5, 1:10, 5:10]
#> + 22/10 edges from fbe66a7 (vertex names):
#>  [1] A--B A--B B--C C--D D--E E--F A--B B--C C--D D--E E--F F--G G--H H--I I--J
#> [16] A--J E--F F--G G--H H--I I--J A--J
E(g)[1, 1:5, 1:10, 5:10] %>% unique()
#> + 10/10 edges from fbe66a7 (vertex names):
#>  [1] A--B B--C C--D D--E E--F F--G G--H H--I I--J A--J
