@ThomasMailund we have a lot of your ‘Beginning Data Science in R’ books available for both current and future data scientists at Scio+
It is great to see that somebody buys them at least. And there’s more there than I ever had myself.
By now, I only have one copy left of the Data Science book and one copy of the Functional Programming book, but still plenty of Metaprogramming and Object-oriented programming.
