Remove Edges from a Network

Description

Remove Edges from a Network

Usage

remove_edges(
  x,
  from,
  to,
  keep_isolates = TRUE,
  keep_format = FALSE,
  directed = NULL
)

Arguments

x	Network input.
from	Source nodes, by label or index.
to	Target nodes, by label or index. The same length as from.
keep_isolates	Logical. Keep nodes that end up with no edges? Default TRUE, matching filter_edges.
keep_format	Logical. Return the input format when TRUE.
directed	Logical or NULL. If NULL (default), auto-detect.

Value

A cograph_network without those edges, or the input format when keep_format = TRUE. Named pairs that carry no edge are reported in a cograph_no_such_edge warning.
