Chapter 5 | Functional Programming
R as a functional programming language R can be considered as a functional programming language as it focusses on the creation and manipulation of functions and has what’s known as first class functions. In computer science, functional programming is a programming...Chapter 4 | Functions
Functions structure When working with R we all make constant use of functions and, when developing, we create new functions so that functions look like very familiar R objects. Nevertheless, understanding the theory and the rationals underlying R functions may help to...Chapter 3 | Environments
Introduction Assuming that we are all familiar with classic R objects such as vectors, matrices, lists, data.frames, etc …, this chapter takes into consideration a critical type of objects: environments. Within the R computation mechanism, environments play a crucial...Chapter 2 | How R works
The ‘’read parse evaluate’’ loop The ‘’read parse evaluate’’ loop is at the core of the R system. Understanding this mechanism and being able to manage and control it is a key point for writing efficient R codes. When we type R commands, two things happen: those...We are part of
