In ivt-baug-ethz/brouterR: Wrapper functions for running the brouter server

Parallel routes calculation

Description

Calculate routes with parallel routine for improved speed. The output is a dataframe containing the travel times, distance, total elevation gain, upward and downward slope and energy expenditure for the route The calculated values are a summary of the detailed csv-file that brouter outputs at a route request. The original file can be called with the calculateRoute function or visualized online at http://www.brouter.de/brouter-web by clicking on the Data option after calculating a route.
