The free and easy-to-use website www.regex101.com serves as a goto sandbox when you are trying different approaches and need immediate feedback. See Figures 12-1 and 12-2. It is not specifically tuned to R, but the great majority of R regex configurations will be properly evaluated. To the right of the screen, explanatory comments are provided. Although it has far fewer features than Regex Buddy (discussed later), for many people, it will be sufficient. Since doing is closely tied to learning, spending a few hours with this tool on the front end will accelerate your learning curve.
