Extract a custom subnetwork from a large network

Usage

subnetwork(
  network,
  nodes = NULL,
  order = 1L,
  mode = "all",
  mindist = 0L,
  return_df = TRUE
)

network: Either an OmniPath interaction data frame, or an igraph graph object.
nodes: Character or integer vector: names, identifiers or indices of the nodes to build the subnetwork around.
order: Integer: order of neighbourhood around nodes; i.e., number of steps starting from the provided nodes.
mode: Character: "all", "out" or "in". Follow directed edges from the provided nodes in any, outbound or inbound direction, respectively.
mindist: Integer: The minimum distance to include the vertex in the result.
return_df: Logical: return an interaction data frame instead of an igraph object.

A network data frame or an igraph object, depending on the ``return_df`` parameter.
