Exercise 3Getting startedPart 1: Essential pandemic constructionPart 2: ReflectionPart 3: Turning everything inAdvanced Users
You can work individually or in pairs. If you work in pairs, you may submit one assignment for the two of you. It is, of course fine if you talk with and work with more than one other person, but I'm capping it as two submitters assignment so I don't end up grading two assignments total.
The New York City Department of Buildings (DOB) maintains a list of construction sites that have been categorized as “essential” during the city’s shelter-in-place pandemic order. They’ve provided an interactive map here where you can see the different projects. There’s also a link there to download the complete dataset.
For this exercise, you’re going to use this data to visualize the amounts or proportions of different types of essential projects in the five boroughs of New York City (Brooklyn, Manhattan, the Bronx, Queens, and Staten Island).
Either create a new project for this exercise only, or make a project for all your work in this class.
You’ll need to download one CSV file and put it somewhere on your computer or upload it to RStudio.cloud—preferably in a folder named data in your project folder. You can download the data from the DOB’s map, or use this link to get it directly:
You may need to right-click and select "Download linked file" if you find that clicking on this link opens a window of incomprehensible text.
To help you, I’ve created a skeleton R Markdown file with a template for this exercise, along with some code to help you clean and summarize the data. Download that here and include it in your project:
In the end, the structure of your project directory should look something like this:
xyour-project-name\03_exercise.Rmdyour-project-name.Rprojdata\EssentialConstruction.csv
To check that you put everything in the right places, you can instead download and unzip this file, which contains everything in the correct structure:
Make the following plots:
The examples from 08-01 and 08-02 will be extremely helpful!
You’ll need to insert your own code chunks where needed. Rather than typing them by hand (that’s tedious and you might miscount the number of backticks!), use the “Insert” button at the top of the editing window, or type ctrl + alt + i on Windows, or ⌘ + ⌥ + i on macOS.
At the bottom of your document, answer the following four questions:
When you’re all done, click on the “Knit” button at the top of the editing window and create an HTML or Word version (or PDF if you’ve installed tinytex) of your document. Upload that file to Blackboard.
There will be a quick "quiz" on BB. Again, if you're working with a buddy, one quiz can apply to both people.
Upon reflection, I think most advanced users will still get something out of this assignment. Specifically, I'd encourage you experiment with color schemes and labels, as described above.
However, if you'd like a different sort of challenge, you can complete an alternate assignment: create a demo/tutorial on a feature that we won't be able to directly explore in class:
Select a prodedure/pacakge from the list and sign up to "claim" it. (I'm also open to other suggestions if you e-mail me)
Create a simple working demonstration using data that might be relevant to our class. I would recommend blscrapeR; wdi, or our TidyTuesday data. (This is not a requirement)
reprex() package to ensure your example is reproducibleCreate a short video in which you "demo" the package, providing clear explanation to relatively new users about how to utilize the package.
Upload the demonstration code, output file (pdf/html), and link to the video. I'll share these on blackboard as resources for your classmates!
