Subgraph of a graph

induced.subgraph() was renamed to induced_subgraph() to create a more consistent API.

Usage

induced.subgraph(
  graph,
  vids,
  impl = c("auto", "copy_and_delete", "create_from_scratch")
)

Arguments

graph

The original graph.

vids

Numeric vector, the vertices of the original graph which will form the subgraph.

impl

Character scalar, to choose between two implementation of the subgraph calculation. ‘copy_and_delete’ copies the graph first, and then deletes the vertices and edges that are not included in the result graph. ‘create_from_scratch’ searches for all vertices and edges that must be kept and then uses them to create the graph from scratch. ‘auto’ chooses between the two implementations automatically, using heuristics based on the size of the original and the result graph.
