Add or Change Edge Attributes

Source: R/wrangle-edit.R
mutate_edges.Rd

Evaluates expressions against the edge table and stores the results as edge columns.

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.
