ANSWER ALL QUESTIONS

https://dataverse.harvard.edu/api/access/datafile/4442012

In this exercise, we assume that twitter_data is an SQL database.

Write an R function, tweet_summary, that accepts user a character string of a Twitter user and returns a numeric vector containing the median number of replies, retweets, and likes for all the tweets in twitter_data posted by user. Extracting data from twitter_data should strictly be done using SQL statements (via sqldf). (4 pts)
