Extract summary stats for temporal network node properties, in parallel

parallel_summarise_temporal_node_properties() calculates summary statistics for a selected node property, over a list of networks. Optionally, identifiers of the nodes with maximum values of the selected node property can also be returned. This function uses a socket cluster with n_threads threads to run calculations in parallel.

Usage

parallel_summarise_temporal_node_properties(
  networks,
  n_threads,
  node_property,
  statistics,
  identify_nodes = FALSE
)

Arguments

networks

A list containing movement networks (networkDynamic objects)

n_threads

Numeric indicating number of threads over which to parallelise.

node_property

Character indicating the network metric for which to calculate summary statistics. One of "forward reachability", "temporal degree", "temporal indegree", or "temporal outdegree".

statistics

A list with summary function(s) to calculate for the selected node_property. For example, list(median, max = max).

identify_nodes

A logical indicating whether you want to identify the nodes with maximal values for node_property in each network. Default is FALSE. Requires that max is included as a named function within statistics.

Value

A named list of lists. For each network, a list consisting of: (1) a named list summary_statistics, with the selected node property summary statistic(s), (2 - only if identify_nodes is set as TRUE) a named character vector node_pid_with_max_value, with the persistent identifier(s) of the node(s) with maximal value(s) for the selected node property.
