Case studies are featured throughout along with examples for each technique presented. R code and solutions to exercises featured in the book are provided on a supporting website.
A good book about web scraping. There were a couple of chapters I didn't read because I wasn't interested (I dont need text mining, for example). Some links and methods are broken or outdated, but I suppose that's normal in a software book. I considered I went from being a low-level amateur in R to being that plus a low-level amateur in scraping that knows the basics and can progress from there when it's needed.
