Learning R Programming

Chapter 6. Working with Strings

In the previous chapter, you learned many built-in functions in several categories to work with basic objects. You learned how to access object classes, types, and dimensions; how to do logical, math, and basic statistical calculations; and how to perform simple analytic tasks such as root solving. These functions are the building blocks of our solution to specific problems.

String-related functions are a very important category of functions. They will be introduced in this chapter. In R, texts are stored in character vectors, and a good number of functions and techniques are useful to manipulate and analyze texts. In this chapter, you will learn the basics and useful techniques of working with strings, including ...
