Add Nodes to a Network

Appends new nodes, identified by label, to a network. A label that already exists raises a cograph_bad_selection error.

Usage

add_nodes(x, labels, ..., keep_format = FALSE, directed = NULL)

Arguments

x

Network input.

labels

Character vector of labels for the new nodes.

...

Named vectors of node attributes for the new nodes, each of length 1 (recycled) or length(labels). Columns the network does not already have are created and filled with NA for the existing nodes.

keep_format

Logical. Return the input format when TRUE.

directed

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

Value

A cograph_network with the new nodes appended (isolated until edges are added), or the input format when keep_format = TRUE.

Examples

add_nodes(regulation_net, labels = "Revise")
#> Cograph network: 11 nodes, 30 edges ( directed )
#> Source: matrix 
#>   Nodes (11): Explore, Plan, Monitor, Adapt, Reflect, Discuss, ... +5 more
#>   Edges: 30 / 110 (density: 27.3%)
#>   Weights: [0.050, 0.490]  |  mean: 0.265
#>   Strongest edges:
#>     Share -> Monitor  0.490
#>     Plan -> Evaluate  0.490
#>     Evaluate -> Adapt  0.430
#>     Synthesize -> Reflect  0.420
#>     Plan -> Discuss  0.400
#> Layout: none 
#>   Use as.data.frame() for the edge table, as.data.frame(what = "nodes") for the nodes.
