R Data Analysis Projects

Overview of this book

R offers a large variety of packages and libraries for fast and accurate data analysis and visualization. As a result, it’s one of the most popularly used languages by data scientists and analysts, or anyone who wants to perform data analysis. This book will demonstrate how you can put to use your existing knowledge of data analysis in R to build highly efficient, end-to-end data analysis pipelines without any hassle. You’ll start by building a content-based recommendation system, followed by building a project on sentiment analysis with tweets. You’ll implement time-series modeling for anomaly detection, and understand cluster analysis of streaming data. You’ll work through projects on performing efficient market data research, building recommendation systems, and analyzing networks accurately, all provided with easy to follow codes. With the help of these real-world projects, you’ll get a better understanding of the challenges faced when building data analysis pipelines, and see how you can overcome them without compromising on the efficiency or accuracy of your systems. The book covers some popularly used R packages such as dplyr, ggplot2, RShiny, and others, and includes tips on using them effectively. By the end of this book, you’ll have a better understanding of data analysis with R, and be able to put your knowledge to practical use without any hassle.

Summary


We started the chapter with an overview of recommender systems. We introduced our retail case and the association rule mining algorithm. Then we applied association rule mining to design a cross-selling campaign. We went on to understand weighted association rule mining and its applications. Following that, we introduced the HITS algorithm and its use in transaction data. Next, we studied the negative association rules discovery process and its use. We showed you different ways to visualize association rules. Finally, we created a small web application using R Shiny to demonstrate some of the concepts we learned.

In the next chapter, we will look at another recommendation system algorithm called content based filtering. We will see how this method can help address the famous cold start problem in recommendation systems. Furthermore, we will introduce the concept of fuzzy ranking to order the final recommendations.
