Calculate a constrained page-rank score — rs_constrained_page

This function can be used to get constrainted personalised page-rank scores akin to Ruiz, et al. You can provide optionally sink_nodes (node types that will force a reset) and/or sink_edges (edge types that will force a reset).

Usage

rs_constrained_page_rank(
  node_names,
  node_types,
  from,
  to,
  weights,
  edge_type,
  personalised,
  sink_nodes,
  sink_edges
)

Arguments

node_names: String vector. Name of the graph nodes.
node_types: String vector. The node types.
from: String vector. The names of the from edges from the edge list.
to: String vector. The names of the to edges from the edge list.
weights: Numerical vector. The edge weights from the edge list.
edge_type: String vector. The edge types.
personalised: Numerical vector. The reset values. They must sum to 1 and be of same length of node_names!
sink_nodes: Optional string vector. Should these node types be seen as sinks, i.e., the reset occurs when this node is reached.
sink_edges: Optional string vector. Shall an automatic reset occur when this edge type is traversed.

Value

The personalised constrained page rank values.
