Hands-On Exploratory Data Analysis with R

By: Radhika Datar, Harish Garg

Overview of this book

Hands-On Exploratory Data Analysis with R will help you build a strong foundation in data analysis and get well-versed with elementary ways to analyze data. You will learn how to understand your data and summarize its characteristics. You'll also study the structure of your data, and you'll explore graphical and numerical techniques using the R language. This book covers the entire exploratory data analysis (EDA) process—data collection, generating statistics, distribution, and invalidating the hypothesis. As you progress through the book, you will set up a data analysis environment with tools such as ggplot2, knitr, and R Markdown, using DOE Scatter Plot and SML2010 for multifactor, optimization, and regression data problems. By the end of this book, you will be able to successfully carry out a preliminary investigation on any dataset, uncover hidden insights, and present your results in a business context.

Summary

In this chapter, we focused on the implementation of the R Markdown feature, which is considered important from a report-generation point of view. We have listed some of the various packages that are available for reading in various kinds of attributes, within the mentioned dataset in R. There are lot of different options, and even the options we have listed have a wide functionality that we are going to cover and use as we go further through the book.

In the next chapter, we will take a real-world univariate and control dataset and run a complete exploratory data analysis workflow on it using the R packages and techniques we have already covered.
