Question 1

Question 3

Make a dotchart in R showing the results of the previous question. Hint: You can use your work from SQL, and export the results to a dataframe called myDF in R. Then you can use something like:

# use a dbGetQuery here, to import the SQL results to R, and then
myresults <- myDF$rating
names(myresults) <- myDF$primary_title
dotchart(myresults)

Make a dotchart that shows how many movies premiered in each year. Now make another dotchart, which shows the same data (i.e., how many movies premiered each year) but only since the year 2000.

Question 6

Among the three big New York City airports (JFK, LGA, EWR), which of these airports had the worst DepDelay (on average) in 2005? (Can you solve this with 1 line of R, using a tapply (rather than using 3 separate lines of R)? Hint: After you run the tapply, you can index your results using [c("JFK", "LGA", "EWR")] to lookup all 3 airports at once.)

Question 7

LIKE is a very powerful tool. You can read about SQLite’s version of LIKE here. Use LIKE to analyze the primary_title of all IMDB titles: First determine how many titles have Batman anywhere in the title, and then determine how many titles have Superman anywhere in the title? Which one occurs more often?

Question 8

How much money was donated during the 2000 federal election cycle by people who have PURDUE listed somewhere in their employer name? How much money was donated by people who have MICROSOFT listed somewhere in their employer name? Hint: You might use the grep or the grepl (which is a logical grep) to solve this one.
