Remove Nodes from a Network

Deletes nodes and every edge incident to them. A node that is not in the network raises a cograph_bad_selection error.

Usage

remove_nodes(x, nodes, keep_format = FALSE, directed = NULL)

Arguments

x

Network input.

nodes

Node labels or indices to remove.

keep_format

Logical. Return the input format when TRUE.

directed

Logical or NULL. If NULL (default), auto-detect.

Value

A cograph_network without those nodes and without any edge that touched them, or the input format when keep_format = TRUE.

Examples

remove_nodes(regulation_net, nodes = "Share")
#> Cograph network: 9 nodes, 24 edges ( directed )
#> Source: matrix 
#>   Nodes (9): Explore, Plan, Monitor, Adapt, Reflect, Discuss, ... +3 more
#>   Edges: 24 / 72 (density: 33.3%)
#>   Weights: [0.050, 0.490]  |  mean: 0.250
#>   Strongest edges:
#>     Plan -> Evaluate  0.490
#>     Evaluate -> Adapt  0.430
#>     Synthesize -> Reflect  0.420
#>     Plan -> Discuss  0.400
#>     Create -> Evaluate  0.390
#> Layout: none 
#>   Use as.data.frame() for the edge table, as.data.frame(what = "nodes") for the nodes.
