Load a network saved with save_network()

load_network.Rd

Reads the network and checks it with validate_network(), so a file from an older version of the contract gives a clear error here instead of a failure in a later function.

Usage

load_network(file)

Arguments

file

path of an .rds file written by save_network()

Value

the network: list of nodes and edges, plus provenance and regulators when it had them
