Source: R/network-utils.R
select_neighbors.Rd

Select nodes within a specified distance from focal nodes.

Usage

select_neighbors(
  x,
  of,
  order = 1L,
  ...,
  keep_edges = c("internal", "none"),
  keep_format = FALSE,
  directed = NULL
)

Arguments

x

Network input.

of

Character or integer. Focal node(s) by name or index.

order

Integer. Neighborhood order (1 = direct neighbors). Default 1.

...

Additional filter expressions to apply after neighborhood selection.

keep_edges

How to handle edges. Default "internal".

keep_format

Logical. Keep input format? Default FALSE.

directed

Logical or NULL. Auto-detect if NULL.

Value

A cograph_network with nodes in the neighborhood.

Examples

select_neighbors(regulation_net, of = "Plan")
#> Cograph network: 7 nodes, 15 edges ( directed )
#> Source: matrix 
#>   Nodes (7): Plan, Monitor, Discuss, Synthesize, Evaluate, Create, Share
#>   Edges: 15 / 42 (density: 35.7%)
#>   Weights: [0.070, 0.490]  |  mean: 0.273
#>   Strongest edges:
#>     Share -> Monitor  0.490
#>     Plan -> Evaluate  0.490
#>     Plan -> Discuss  0.400
#>     Create -> Evaluate  0.390
#>     Monitor -> Create  0.370
#> Layout: none 
#>   Use as.data.frame() for the edge table, as.data.frame(what = "nodes") for the nodes.
