RStudio for R Statistical Computing Cookbook

By: Andrea Cirillo

Overview of this book

The requirement of handling complex datasets, performing unprecedented statistical analysis, and providing real-time visualizations to businesses has concerned statisticians and analysts across the globe. RStudio is a useful and powerful tool for statistical analysis that harnesses the power of R for computational statistics, visualization, and data science, in an integrated development environment. This book is a collection of recipes that will help you learn and understand RStudio features so that you can effectively perform statistical analysis and reporting, code editing, and R development. The first few chapters will teach you how to set up your own data analysis project in RStudio, acquire data from different data sources, and manipulate and clean data for analysis and visualization purposes. You'll get hands-on with various data visualization methods using ggplot2, and you will create interactive and multidimensional visualizations with D3.js. Additional recipes will help you optimize your code; implement various statistical models to manage large datasets; perform text analysis and predictive analysis; and master time series analysis, machine learning, forecasting; and so on. In the final few chapters, you'll learn how to create reports from your analytical application with the full range of static and dynamic reporting tools that are available in RStudio so that you can effectively communicate results and even transform them into interactive web applications.

Building a rotating 3D graph and exporting it as a GIF


When dealing with complex datasets, having the possibility to show your data in a 3D environment can be really enhancing.

This recipe will show you how to create such a plot, animate it, and export your animation as a GIF.

Getting ready

This recipe will leverage the rgl package specifically developed for 3D visualizations in R:

install.packages("rgl")
library(rgl)

We will also need to install ImageMagick in order to perform the export into the GIF format.

You can find instructions for software installation at http://www.imagemagick.org/script/binary-releases.php.

As an explicative dataset, we will use the iris dataset, which is a built-in dataset available with all base R installations.

The iris dataset is one of the most used datasets in R tutorials and learning sessions, and it is derived from a 1936 paper by Ronald Fisher, named The use of multiple measurements in taxonomic problems.

Data was observed on 50 samples of 3 species of the iris...
