clear_dodgr_cache: Remove cached versions of 'dodgr' graphs.

In dodgr: Distances on Directed Graphs

Remove cached versions of dodgr graphs.

Description

This function should generally not be needed, except if graph structure has been directly modified other than through dodgr functions. Graphs are cached based on a hash of the edge_id, d, d_weighted, time, and time_weighted columns, so manual changes to any of those will be detected automatically. Manual changes to any other column or attribute (for example, from/to vertex identifiers) will not be reflected in the hash, and so will not necessarily be translated into changes in dodgr output unless the cached versions are cleared using this function. See https://github.com/UrbanAnalyst/dodgr/wiki/Caching-of-streetnets-and-contracted-graphs # nolint for details of caching process.

Usage

clear_dodgr_cache()

Value

Nothing; the function silently clears any cached objects

Examples

clear_dodgr_cache ()
# Then call dodgr functions as usual:
graph <- weight_streetnet (hampi, wt_profile = "foot")
