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

Examples

adj <- matrix(c(0, 1, 1, 1, 0, 1, 1, 1, 0), 3, 3)
rownames(adj) <- colnames(adj) <- c("A", "B", "C")

remove_nodes(adj, nodes = "B")
#> Cograph network: 2 nodes, 1 edges ( undirected )
#> Source: matrix 
#>   Nodes (2): A, C
#>   Edges: 1 / 1 (density: 100.0%)
#>   Weights: [1.000, 1.000]  |  mean: 1.000
#>   Strongest edges:
#>     A -- C  1.000
#> Layout: none 
#>   Use as.data.frame() for the edge table, as.data.frame(what = "nodes") for the nodes.
