Decompose a graph into components

Creates a separate graph for each component of a graph.

Keywords
graphs
Usage
decompose(graph, mode = c("weak", "strong"), max.comps = NA,
  min.vertices = 0)
Arguments
graph

The original graph.

mode

Character constant giving the type of the components, wither weak for weakly connected components or strong for strongly connected components.

max.comps

The maximum number of components to return. The first max.comps components will be returned (which hold at least min.vertices vertices, see the next parameter), the others will be ignored. Supply NA here if you don't want to limit the number of components.

min.vertices

The minimum number of vertices a component should contain in order to place it in the result list. Eg. supply 2 here to ignore isolate vertices.

Value

A list of graph objects.

See Also

is_connected to decide whether a graph is connected, components to calculate the connected components of a graph.

# NOT RUN {
# the diameter of each component in a random graph
g <- sample_gnp(1000, 1/1000)
components <- decompose(g, min.vertices=2)
sapply(components, diameter)
# }
