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 data from R


The Instagram API provides access to some amazing content published on Instagram. It uses the OAuth 2.0 protocol for authentication and authorization as explained in the previous section. Let's see the functions present in the package instaR, which enables us to download data from R.

Searching public media for a specific hashtag

The function searchInstagram allows the users to download the public media posted on Instagram with a specific hashtag:

MachuPicchu<- searchInstagram("MachuPicchu", token, n=10, folder="MachuPicchu")

The preceding code will return the recent public media posts on Instagram with the hashtag MachuPicchu, and the media files will be downloaded in a folder named MachuPicchu (as specified in the preceding code) in the current working directory of R. The working directory of R can be changed using the function setwd(). You can explore the content downloaded using the below code. The function names will give the various columns present in the data:
