Mastering Social Media Mining with R

Overview of this book

With an increase in the number of users on the web, the content generated has increased substantially, bringing in the need to gain insights into the untapped gold mine that is social media data. For computational statistics, R has an advantage over other languages in providing readily-available data extraction and transformation packages, making it easier to carry out your ETL tasks. Along with this, its data visualization packages help users get a better understanding of the underlying data distributions while its range of "standard" statistical packages simplify analysis of the data. This book will teach you how powerful business cases are solved by applying machine learning techniques on social media data. You will learn about important and recent developments in the field of social media, along with a few advanced topics such as Open Authorization (OAuth). Through practical examples, you will access data from R using APIs of various social media sites such as Twitter, Facebook, Instagram, GitHub, Foursquare, LinkedIn, Blogger, and other networks. We will provide you with detailed explanations on the implementation of various use cases using R programming. With this handy guide, you will be ready to embark on your journey as an independent social media analyst.

Building a heterogeneous dataset using the most active users


Let's build a heterogeneous dataset based on the public repositories created by the most active users of GitHub. As we know how to extract data using the package rgithub, we will explore the other method too, for example, directly using the API's URL. In this method, we need to pass the API URL to the function fromJSON, which has a dependency on the package jsonlite. The API URL will also work from the browser and will be checked for accuracy of the data. Those URLs will return data in JSON format.

The most active users of GitHub will be obtained through the following URL, or you can use the CSV file named TopUsers.csv, which also holds the data of users who were active as of July 2015. We will make use of the username to pull the additional data about the users.

Use the function read.csv to read the active users file from https://gist.github.com/paulmillr/2657075/ and read the username column as characters using the function as...
