Want to learn how to make maps in R?

Once upon a time I wrote an open source package that makes it easy to create choropleth maps in R. I called the package choroplethr.

Then I created a free email course to teach people how to use the software. That course is called Learn to Map Census Data in R, and has been taken by thousands of people.

People who took that course asked me a lot of questions about choroplethr. In particular, they were wanted to know about using choroplethr to make international maps. So I created a separate course for them. That course is called Mapmaking in R with Choroplethr. It sold for $99 and was very popular. Here’s an image from that course


People who took that course wound up having a lot of questions too. In particular, they wanted to learn how to work with shapefiles. So I made a separate course for them: Shapefiles for R Programmers. That course also sold for $99 and was well received. Here’s an image from that course:


Today you can buy both courses for $1 (a $197 savings)

Last week I decided to stop offering the courses for individual sale, and instead make them part of my new membership.

The membership normally costs $49 a month. But to celebrate this change, I have decided to offer a 1 month trial for only $1. This offer ends Thursday, September 1. This brings your total savings to $246.

Why are you bundling the courses with the membership site?

Because the membership provides a better environment for learning.

In addition to the courses, members have a private forum where they can ask questions, and bi-monthly live office hours where we can discuss the courses and other issues.

Can I ask other questions in the membership?


The membership exists to help people create, publish and profit from R projects. Anything related to that theme is fair game.

Will you be creating more courses in the future?

That’s the plan. And they will be added to the membership library. In that sense, the value of the membership will increase over time.

Like before, I will decide the topic for new courses based on feedback from members / people who took previous courses.

How can I learn more?

The sale is now over, but you can still register here:
