Import users
As you might have guessed by now, the database contains data on a more tasty version of Twitter, namely Tweater. Users can post tweats with short recipes for delicious snacks. People can comment on these tweats. There are three tables: users, tweats, and comments that have relations among them. Which ones, you ask? You'll discover in a moment!
Let's start by importing the data on the users into your R session. You do this with the dbReadTable()
function. Simply pass it the connection object (con
), followed by the name of the table you want to import. The resulting object is a standard R data frame.
