It’s very hard to write expressive, readable code that munges some horrible tabular format into another arbitrary tabular format, to be fair. That said it’s true that most R code doesn’t seem like map/reduce, or some other pipeline of transformations. It’s usually more like someone cut and pasted a long, hard REPL session into a notebook and has no intention of ever scrolling back up.
