rCharts + Leaflet + KML by ramnathv

This is a demo of using rCharts to create a Leaflet map using KML. It requires you to install the latest dev branch of rCharts, which can be done using install_github("rCharts", "ramnathv", ref = "dev"). The code to reproduce this chart is shown below

# download kml example file
require(downloader)
download(
  url = "http://harrywood.co.uk/maps/examples/leaflet/mapperz-kml-example.kml",
  destfile = "mapperz-kml-example.kml"
)

# initialize leaflet chart and add kml
L1 <- Leaflet$new()
L1$addKML("mapperz-kml-example.kml")
L1$save('index.html', cdn = TRUE)

Note that you will not be able to view the map as static HTML. So fire up a local server from the same directory where you saved your html file and the kml file.

$ python -m SimpleHTTPServer 8000

and navigate to http://localhost:8000/index.html
