Rachel S.
Answer:

To install a package in RStudio, first, find the pane that includes the "Packages" tab, and click on it. In the top left corner of the pane, there is an "Install" button. Type in the name of the package you need, and click "Install." You will see the code running in your Console pane, which is how you know it is working. Once it is finished, you simply need to use the library() function with the name of the package within the parenthesis in your Console.
