Hands-On Data Science with R

By: Vitor Bianchi Lanzetta, Doug Ortiz, Nataraj Dasgupta, Ricardo Anjoleto Farias

Overview of this book

R is the most widely used programming language, and when used in association with data science, this powerful combination will solve the complexities involved with unstructured datasets in the real world. This book covers the entire data science ecosystem for aspiring data scientists, right from zero to a level where you are confident enough to get hands-on with real-world data science problems. The book starts with an introduction to data science and introduces readers to popular R libraries for executing data science routine tasks. This book covers all the important processes in data science such as data gathering, cleaning data, and then uncovering patterns from it. You will explore algorithms such as machine learning algorithms, predictive analytical models, and finally deep learning algorithms. You will learn to run the most powerful visualization packages available in R so as to ensure that you can easily derive insights from your data. Towards the end, you will also learn how to integrate R with Spark and Hadoop and perform large-scale data analytics without much complexity.

Looking for patterns – peeking, visualizing, and clustering data

This is the analysis step. Some people would refer it as the actual data mining, or, in this case, text mining. For other people, we have been doing text mining for a long time now. Terminology aside, we have a clean and transformed dataset (clean_dt) that very much speaks for itself.

The features displayed by the tibble might be useful for some people already. It is for me, as I can drive my studies and seek some more R adventures. Yet, the analysis could be deepened with no troubles; data mining is never about getting enough knowledge, but about maximizing the amount of insight we can get given our computing and time constraints.

As you get skilled and experienced, you can get and deliver more out from it. In this section, we will depart from our clean dataset to do the following:

  • Draw some descriptive...
