An R swirl course on how to create maps with leaflet
This course will teach you how to create maps with R leaflet. If you find mistakes, have suggestions, lesson requests or any other type of feedback send me an email to [email protected]. My blog with other R howtos and other things I do in data science can be found at http://blog.haunschmid.name.
I planned the lectures in the following order but it's up to you. If you've never used R leaflet I recommend starting with Lesson 1. If you've never used R before or are interested in other courses, also check out (https://github.com/swirldev/swirl_courses). They provide you with beginner and advanced courses.
Lesson content: Basic usage of leaflet(), addTiles(), addMarkers(), setView() and the pipe operator %>%.

If your run into any problems because of the german letters ä, ö, ü, please tell me! I am running RStudio with the locale "en_GB.UTF-8" and it runs without problems. To change your locale, you can use:
Sys.setlocale("LC_ALL", 'en_GB.UTF-8') # Instead of LC_ALL For details check:
?Sys.setlocale
