Select Edges Between Node Sets

Select edges connecting two specified node sets.

Usage

select_edges_between(
  x,
  set1,
  set2,
  ...,
  .keep_isolates = FALSE,
  keep_format = FALSE,
  directed = NULL
)

Arguments

x

Network input.

set1

Character or integer. First node set (names or indices).

set2

Character or integer. Second node set (names or indices).

...

Additional filter expressions.

.keep_isolates

Keep nodes with no edges? Default FALSE.

keep_format

Examples

adj <- matrix(c(0, .5, .8, 0,
                .5, 0, .3, .6,
                .8, .3, 0, .4,
                 0, .6, .4, 0), 4, 4, byrow = TRUE)
rownames(adj) <- colnames(adj) <- c("A", "B", "C", "D")

# Edges between {A, B} and {C, D}
select_edges_between(adj, set1 = c("A", "B"), set2 = c("C", "D"))
#> Cograph network: 4 nodes, 3 edges ( undirected )

#>   Edges: 3 / 6 (density: 50.0%)
#>   Weights: [0.300, 0.800]  |  mean: 0.567
