Obtaining Twitter data
As expected, before analyzing Twitter data, one must obtain the data. One reason we like R for social media mining is that it makes obtaining targeted portions of Twitter data (relatively) simple. Besides having the capacity to read standard data types and files from traditional statistical software packages, R can also read many other specialized formats. For instance, R can read relational databases, Hadoop, and some web formats such as Twitter. This chapter first covers how to obtain Twitter data before describing some simple exploratory data analysis techniques.
To begin ingesting social media data from Twitter, you will need a developer account on Twitter. You can start one (free of cost) at https://dev.twitter.com/apps ...
