My free book has a cover!

I’m currently writing a book as a hobby. It’s titled Functional programming and unit testing for data munging with R and you can get it for free here. You can also read it online for free on my webpage What’s the book about?

Here’s the teaser text:

Learn the basics of functional programming, unit testing and package development for the R programming language in order to make your data tidy!

The book now has a beautiful cover thanks to @putosaure. Putosaure is a Paris based graphic designer who also reviews video games. He is also a very good friend of mine and I am very happy he made this beautiful cover for my book:

In it, we see a guy holding a shield with the Greek letter lambda, which also happens to be the letter to designate functional programming. I’ve added the title with the Komika Title font.

Consider this cover in beta, it’ll probably evolve some more. But I couldn’t wait to use it!

I love it. Hope you’ll love it too!
