Add or Change Edge Attributes

Usage

mutate_edges(
  x,
  ...,
  community = "louvain",
  keep_format = FALSE,
  directed = NULL
)

Arguments

x

Network input.

...

Named expressions evaluated against the edge table, with the same metrics and predicates select_edges() offers, for example strong = abs_weight > 0.5 or scaled = weight / max(weight).

community

Community detection method used when an expression refers to same_community, from_community or to_community. Default "louvain".

keep_format

Logical. Return the input format when TRUE.

directed

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

Value

A cograph_network whose edge table has the new columns, or the input format when keep_format = TRUE.

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")

as.data.frame(mutate_edges(adj, strong = weight > 0.5))
#>   from to weight strong
#> 1    A  B    0.5  FALSE
#> 2    A  C    0.8   TRUE
#> 3    B  C    0.3  FALSE
#> 4    B  D    0.6   TRUE
#> 5    C  D    0.4  FALSE
