AppVeyor Build Status

cyclestreets

The goal of cyclestreets is to provide a simple R interface to the CycleStreets.net routing service.

It was split-out from stplanr for modularity.

Installation

Install the package with devtools as follows:

# install.packages("devtools")
devtools::install_github("Robinlovelace/cyclestreets")

Example

A common need is to get from A to B:

library ("cyclestreets")
# stplanr::geo_code ("leeds rail station") 
from = c(-1.544, 53.794)
# stplanr::geo_code ("leeds university") 
to = c(-1.551, 53.807)
r = cyclestreets::journey(from, to, "balanced")
sf:::plot.sf(r)

To get a key go to https://www.cyclestreets.net/api/apply/

Save the key as an environment varible using export CYCLESTREETS=your_key_here by adding CYCLESTREETS=your_key_here as a new line in your .Renviron file, e.g. with the following command:

usethis::edit_r_environ()

Check the map is good with leaflet:

library(leaflet)
p = colorNumeric("RdYlBu", domain = r$busynance, reverse = TRUE)
leaflet(r) %>% 
  addTiles() %>% 
  addPolylines(color = ~p(busynance), weight = 20, opacity = 0.9) %>% 
  addLegend(pal = p, values = ~busynance)

Route types available are: fastest, quietest, balanced. See help pages such as ?journey and https://www.cyclestreets.net/api/ for details.

You can’t perform that action at this time.
