Do students start whenever they want and just get e-mails as the timeline above suggests? Any prerequisites? Do I have to install R myself or is that covered?
Yes. As soon as you signup you get lesson 1. You have to install R yourself, but lesson 1 covers that.
I believe your example code is missing library(ggplot2).
You are correct and I have updated the post. Thank you.
Great tutorial, thanks for sharing. How can I apply this to a county or local authority in the UK, for instance?
I created a package called choroplethrAdmin1 which shows administrative level 1 maps of every country in the world. (Administrative Level 1 = states/provinces of countries). Here is some documentation of that package, with an examples of the prefectures of Japan.
Additionally, choroplethr is really designed to work with any shapefile. I have two free resources for getting started with that.
If you have further questions I recommend posting on the choroplethr google group.
I wanted to start working through the tutorial and decided to make sure the package chloroplethrMaps was installed and up to date, so ran install.packages(chloroplethrMaps) which gave the messages that the package was not available for R 3.2.2 (package ‘chloroplethrMaps’ is not available (for R version 3.2.2))
It looks like you misspelled the package name:
install.packages(chloroplethrMaps) -> install.packages(“choroplethrMaps”)
