What you need for this book
The code for each chapter has been made available as a project on GitHub at https://github.com/clojuredatascience. The example code can be downloaded as a zip file from there, or cloned with the Git command-line tool. All of the book's examples can be compiled and run with the Leiningen build tool as described in Chapter 1, Statistics.
This book assumes that you're already able to compile and run Clojure code using Leiningen (http://leiningen.org/). Refer to Leiningen's website if you're not yet set up to do this.
In addition, the code for many of the sample chapters makes use of external datasets. Where possible, these have been included together with the sample code. Where this has not been possible, instructions for downloading the data have been provided in the sample code's README file. Bash scripts have also been provided with the relevant sample code to automate this process. These can be run directly by Linux and OS X users, as described in the relevant chapter, provided the curl, wget, tar, gzip, and unzip utilities are installed. Windows users may have to install a Linux emulator such as Cygwin (https://www.cygwin.com/) to run the scripts.
