Practical Data Science Cookbook, Second Edition - Second Edition

Overview of this book

As increasing amounts of data are generated each year, the need to analyze and create value out of it is more important than ever. Companies that know what to do with their data and how to do it well will have a competitive advantage over companies that don’t. Because of this, there will be an increasing demand for people that possess both the analytical and technical abilities to extract valuable insights from data and create valuable solutions that put those insights to use. Starting with the basics, this book covers how to set up your numerical programming environment, introduces you to the data science pipeline, and guides you through several data projects in a step-by-step format. By sequentially working through the steps in each chapter, you will quickly familiarize yourself with the process and learn how to apply it to a variety of situations with examples using the two most popular programming languages for data analysis—R and Python.

Preface

Preparing for analysis


This recipe will prepare the groundwork with the tools you need to complete this project. If you do not have R installed on your computer, please see the instructions in Chapter 1, Preparing Your Data Science Environment.

Getting ready

You need a computer with R installed and an internet connection.

How to do it...

The following steps will get you prepared for the remainder of this chapter by downloading the dataset from the BLS website and ensuring that we have the needed R packages:

  1. Download the 76.8 MB compressed data from http://www.bls.gov/cew/data/files/2012/csv/2012_annual_singlefile.zip , and save it to a location that you will remember.
  2. Uncompress the file by right-clicking on it in explorer or finder, and use the appropriate menu item.

If you are familiar with the command line in the Terminal in Linux/Mac OS X, you can easily uncompress the downloaded file using unzip 2012_annual_singlefile.zip.

  1. Launch the RStudio IDE on your computer (or just plain R for purists...
