This document provides instructions for setting up APIs in R for Facebook, Twitter, and YouTube data. It explains how to download and install R and RStudio, set up the Facebook and Twitter APIs by obtaining app IDs and secrets, and provides code samples to download the first batch of data from each platform, such as 100 Facebook posts or a specified number of tweets. It also discusses saving the social media data to CSV files.

You are all set to mine Facebook data!
By executing the above code, we ask R to download 100 posts sent between
07/05/2016 and 09/11/2016 by the Facebook page UMassAmherst. We set
reactions to TRUE so that R will get the total count of Facebook reactions: love,
haha, wow, sad, angry. The output is named Umass_post.

11. The code creates a data frame named UMass_post. A
data frame is a spreadsheet-list R object.
