# Preface

Before beginning the book, you will need to download the R software www.r-project.org and then the RStudio software www.rstudio.com. R is the brains and RStudio1 is an “IDE” (something that helps us work with R much more easily).

Once both are installed (helps on installing the software can be found on www.rstudio.com, www.r-bloggers.com, and www.statmethods.net) you are good to go. The remainder of the book will be about actually using it.

The book is divided into three parts.

## Part I

1. Chapter 1: The Basics
2. Chapter 2: Working with and Cleaning Your Data
3. Chapter 3: Understanding Your Data (summary statistics, ggplot2)

## Part II

1. Chapter 4: Basic Statistical Analyses (T-tests, ANOVA, Linear Regression)
2. Chapter 5: Generalized Linear Models
3. Chapter 6: Multilevel Modeling
4. Chapter 7: Other Modeling Techniques

## Part III

1. Chapter 8: Advanced data manipulation
At the end of the book, you should be able to: 1) use R to perform your data cleaning and data analyses and 2) understand online helps (e.g. www.stackoverflow.com, www.r-bloggers.com) so your potential in R becomes nearly limitless.
1. Get the free version of Rstudio. Believe me, it doesn’t feel like it should be free software.
