Arrow

<p>An R6 class representing an directed edge in a digraph.</p>

Classes and functions for modelling health care interventions
using decision trees and semi-Markov models. Mechanisms are provided for
associating an uncertainty distribution with each source variable and for
ensuring transparency of the mathematical relationships between variables.
The package terminology follows Briggs "Decision Modelling for Health
Economic Evaluation" (2006, ISBN:978-0-19-852662-9).
