Here is the question:

Do a little bit of research and come up with an example of how R is used. You can describe either a company using R and what they use it for, a news story about how companies are using it, or an interesting package that does some interesting functionality. Write one to three sentences on what you found and the URL where you found it.

(Hint: Just Google “companies using R” or “applications of R” or something like that. Examples aren’t too difficult to find.)

Take a look at the SpotCrime website. Type in a few zip codes to see crime statistics in different areas.

Answer this question:

Describe a situation where you could use a join to retrieve information from a set of tables. For example, if you have orders in one table and customers in another table, you’d need to join those tables to figure out which orders were placed by the customers who lived in Pennsylvania.
