Task 0: Getting started
Create a new RStudio project somewhere on your computer. Remember, in RStudio, “File > New Project ..”)

Download the file below and place it in your new
data/ folder. You’ll probably need to right click on each and choose “Save link as…”.

Download this R Markdown file and place it in your newly-created project Again, you might have to right click on the link and choose “Save link as…”.
It contains an outline/skeleton of the two tasks you’ll need to do in this problem set. Lots of the code is pre-written again!
In the end, the structure of your new project directory should look something like this:
your-project-name\ your-name_problem-set-2.Rmd your-project-name.Rproj data\ Officer_Traffic_Stops.csv CMPD_Police_Divisions\ CMPD_Police_Divisions.cpg CMPD_Police_Divisions.dbf CMPD_Police_Divisions.prj CMPD_Police_Divisions.shp CMPD_Police_Divisions.shx
Task: CMPD Traffic Stops
Follow the instructions in the R Markdown file you downloaded.
You will need to do two things: either write in complete sentences a response or write R code to fill in a chunk.
“xxxxx” = Write, in complete English sentences, your response. 1-2 sentences is sufficient.
“Plot” = Write R code in the chunk corresponding to the instructions.
When you’re done, submit a compressed (zipped) folder of your entire project including the knitted HTML file, R Markdown file, data folder, and RStudio Project of your analysis on Canvas.
To complete the assignment, upload here to Canvas by 11:59pm on March 11, 2018.
It’s best if the final knitted document is clean and free of warnings and messages (so if a chunk is creating messages, like wherever you run
message=FALSE, warning=FALSE to the chunk options).
