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.

Accessing GitHub data from R


Accessing the GitHub data from R is simple. It can be accessed using the package rgithub developed by Carlos Scheidegger, which provides the binding for the GitHub web services API. We can also use the API URL directly in the function fromJSON, which will extract the JSON data in data frame format.

Previously, we saw how to authenticate using the package rgithub; now let's use some of the functions available in the package to pull data from GitHub.

First, let's pull our GitHub account data using the function get.myself and pass the variable ctx as a parameter, which is a GitHub context object holding the authentication results. This function will provide basic details about our account such as date created, last updated, location, e-mail, number of public repositories contributed, following and followers, and also about the number of API calls we have made in the current session. Let's execute the function get.myself and check the output.

get.myself(ctx)
