Editing Statistics and Statistical Programming (Winter 2021)/Problem set 12 (section)

=== PC1. Download, import, and reshape the data ===

* Download the dataset by clicking through on the "Red Dye Number 40" link on [http://college.cengage.com/mathematics/brase/understandable_statistics/7e/students/datasets/owan/frames/frame.html this webpage]. You'll find that the it's not in an ideal setup. It's an Excel file (XLS) with a series of columns labeled X1.. X4. Yikes! If you look at the website with the data and/or Table 1 in the paper you should be able to figure out what each column stands for.
* Import the data into R and get to work on reshaping the dataset. I think a good format would be a data frame with two columns: <code>group</code> (or <code>dose</code>) and <code>weeks_alive</code> but whatever you choose is fine.
