gf_connected_components

Connected components

Description

Computes the connected component membership of each vertex and returns a DataFrame of vertex information with each vertex assigned a component ID.

Usage

gf_connected_components(x, broadcast_threshold = 1000000L,
  algorithm = c("graphframes", "graphx"), checkpoint_interval = 2L,
  ...)

Arguments

Argument Description
x An object coercable to a GraphFrame (typically, a gf_graphframe).
broadcast_threshold Broadcast threshold in propagating component assignments.
algorithm One of ‘graphframes’ or ‘graphx’.
checkpoint_interval Checkpoint interval in terms of number of iterations.
Optional arguments, currently not used.

Examples


# checkpoint directory is required for gf_connected_components()
spark_set_checkpoint_dir(sc, tempdir())
g <- gf_friends(sc)
gf_connected_components(g)
