You have been hired as a business analyst at a local company. Your manager, knowing you have
R expertise, wants to move away from using Excel and wants to instead learn R. They have asked
you to create a one-page document as an executive summary on the big takeaways they need to
know about R.
In particular, they would like to have a brief overview that touches on the following points:
•What is the difference between R and RStudio?
•What are the benefits of using R over Excel?
•What is an Rscript?
•What are R packages? How are they loaded in and when is it necessary to load them?
•What the main data types in R? What is an example of each of these data types?
•I have tried to take an average of a column using the mean function, but I keep getting NA as the
answer—what is wrong here?
•Where can I find help on R?
