| == Programming Challenges ==
| |
|
| |
| Because this is our first week, the programming challenges are setup tasks you can do to prepare you to complete future programming challenges.

|
| |
| :'''PC1.''' Download and install R — You can do that from [https://cran.rstudio.com/ this webpage] where you will have to choose based on your operating system.
| |
| :'''PC2.''' Download and install RStudio — Download from the [https://www.rstudio.com/products/rstudio/download/ the RStudio download page] choosing an option appropriate for your operating systems (e.g., Windows, Mac OSX, or GNU/Linux).
| |
| :'''PC3.''' (a) Create and save a new RStudio "Project" ('.Rproj'). Then, within your new project, (b) create and save a new RMarkdown file ('.Rmd'). Finally, (c) write a combination of text notes and R code in your RMarkdown file and "knit" the output into HTML and PDF. I recommend reproducing and extending some of the examples from the first ''COM520 R Tutorial #2'' such as the following:
| |
| * Complete an arithmetic problem
| |
| * Assign multiple values to a variable.
| |
| * Perform an operation on your variable (e.g., create a variable called <code>x</code> that contains a set of numerical values and multiply it by some other number.
| |
| * Create variables of different classes and get R to tell you the class of each variable using the <code>class()</code> function.
| |
| * Perform a logical comparison on the values of a variable (e.g., can you print the values of the <rivers> dataset that are less than 500?)
| |
| * Install and load a library. Try the <code>openintro</code> package that accompanies our textbook.
| |
| :'''PC4.''' Upload your .Rmd file and knitted .pdf file to [https://canvas.northwestern.edu/courses/122522/assignments/ the appropriate assignment on Canvas].
