Four Kinds of Scoping in R

:: scope, r, by Ming-Ho Yee

In the first and second parts of this blog series, I defined lexical and dynamic scope, and demonstrated interesting cases of scoping in R.

In this third and final part of my blog series, I’d like to discuss a paper by the creators of R, where they motivate the need for lexical scoping in a statistical programming language.

This is a “bonus” blog post, because I’m going to dive into some of the hairier R features to show how four different kinds of scoping can be simulated in R.
