Learn how to manipulate functions and expressions to modify how the R language interprets itself. This book is an introduction to metaprogramming in the R language, so you will write programs to manipulate other programs. Metaprogramming in R shows you how to treat code as data that you can generate, analyze, or modify.
R is a very high-level language where all operations are functions and all functions are data that can be manipulated. This book shows you how to leverage R´s natural flexibility in how function calls and expressions are evaluated, to create small domain-specific languages to extend R within the R language itself.
What You´ll Learn

Look inside a function call

Work with R expressions and environments

Manipulate expressions in R

Use substitutions
