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.

Preface

Chapter 7. Streaming Data Clustering Analysis in R

In all those instances where data is collected from various sources, brought to a centralized location, and stored for analysis, that data is called as data at rest. There is a huge time delay between the time the data was recorded and when the analysis was performed. Analyzing the last 6 months' inventory data is an example of data at rest. Today, majority of data analysis is performed using data at rest.

With the number of Internet of Things projects on the rise, there is a great demand today to perform analysis on data in motion, also called streaming data. Streaming data is becoming ubiquitous with the number of addressable sensors and devices being added to the internet. As an example from computer network monitoring: an intrusion detection system analysis, the network packets received in real time to quickly determine if the system is compromised and takes an appropriate action. Latency is key when analyzing data in motion.
