This is a basic example which shows you how to solve a common problem:

library(r5rgui)
r5r_gui_demo()

r5gui demo in action

What the demo runs internally is this simple example code:

data_path <- system.file("extdata/poa", package = "r5r")
r5r_network <- build_network(data_path = data_path, verbose = FALSE)
r5r_gui(r5r_network, center = c(-51.22, -30.05), zoom = 11)

Therefore you can replace data_path with your own data path and explore your own routing network.
