I just finished an additional chapter in Object-oriented Programming in R. I’m trying to make it just a little longer before I try to sell it to a publisher.
If you have bought it on Amazon it should be updated automatically. Well, if you bought the Kindle version; obviously, paperbacks are not updated automatically. Still, if you have bought the paperback you get the ebook for free, so you can still get it there. I am uploading a new paperback version as well right now, but wait a few days before ordering; I don’t know how fast the new file becomes the one they print.
In any case, since people have also bought the book on Leanpub, I don’t want to make this chapter exclusive to Amazon, although the book is signed up with Kindle Select, so everyone can just download it here.
