Please upload your final completed lab on the Assignments page in Canvas, as per the instructions below.
You are welcome and expected to ask for help from the instructors if you get stuck: Please also come to the R Bootcamp on Friday—there is coffee and snacks!
In this lab, we will continue to work with data from the Harry Potter series of moving pictures.

Refer back to your answers for Basic Building Blocks lab. You may use the numeric vectors you coded there.
Which movie/s had a Production Budget of more than $150,000,000? Generate a vector of logical statements.
Which movie/s had a Worldwide Box Office of less than $900,000,000? Generate a vector of logical statements.
Which movies return on investment (i.e., worldwide box office - production budget) was over $500,000,000?
Create a named vector of all the Movie names called
Is there a way we could create this vector programatically. (Well, yes, otherwise I wouldn’t ask the question …).
Look at the names of the movies. What string is common to almost all of them?
Thus, one approach is to create an object containing the text string “Harry Potter and the”. Call this string
Create a vector with the specific title section for each movie 1–8 (e.g., “Sorcerer’s Stone” for movie 1), called
Combine the vectors
hp_titles to create a vector of 8 elements for the full titles of the first 8 movies. Call this vector
Add a 9th element to this vector for the title of the 9th movie.
