The goal of {r5rgui} is to allow the user to interactively explore routes calcualted with {r5r} package in a Shiny app, e.g. for troubleshooting routing problems.

Get it from CRAN:

install.packages("r5rgui")

Or get the latest development version from R-Universe:

install.packages(
  "r5rgui",
  repos = c("https://e-kotov.r-universe.dev", "https://cloud.r-project.org")
)

You can also install the development version of {r5rgui} from GitHub with:

# install.packages("pak")
pak::pak("e-kotov/r5rgui")

Also setup Java as as you would for r5r package:

# install.packages('rJavaEnv') # if not installed yet

# install and use Java 21 in current session
rJavaEnv::use_java(21)

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

library(r5rgui)
r5r_gui_demo()

What the demo runs internally is this simple example code:

library(r5r)
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.
