In dodgr: Distances on Directed Graphs

Estimate a value for the 'dist_threshold' parameter of the dodgr_centrality function.

Description

Providing distance thresholds to this function generally provides considerably speed gains, and results in approximations of centrality. This function enables the determination of values of 'dist_threshold' corresponding to specific degrees of accuracy.

Usage

estimate_centrality_threshold(graph, tolerance = 0.001)

Arguments

graph	'data.frame' or equivalent object representing the network graph (see Details)
tolerance	Desired maximal degree of inaccuracy in centrality estimates values will be accurate to within this amount, subject to a constant scaling factor. Note that threshold values increase non-linearly with decreasing values of 'tolerance'

Value

A single value for 'dist_threshold' giving the required tolerance.

Note

This function may take some time to execute. While running, it displays ongoing information on screen of estimated values of 'dist_threshold' and associated errors. Thresholds are progressively increased until the error is reduced below the specified tolerance.
