This course will provide “hands-on” training for learning how to analyze data in the R statistical software package. We will cover data input/output, data management and manipulation, and how to make useful and informative graphics.
Objectives
By the end of the course, students should be comfortable:
- Reading data into R
- Recoding and manipulating data
- Using R add-on packages
- Making exploratory plots
- Performing basic statistical tests
- Understanding basic programming syntax
- Creating reproducible R documents

Course Format
Each class will consist of 2 or 3 hour-long modules.
Each module features a lecture and an R programming lab, where students apply the skills taught in the modules to real data in breakout rooms.
Class sessions will be recorded and later posted.
If you have a question not covered during class, please post it on Slack. This allows everyone to see it. If another student does not answer your question (which we encourage!), we will try to answer it within 24 hours. If you feel uncomfortable posting a question publicly, let a TA or instructor know your question and we will post it for you anonymously.
To get the most out of this class, if possible, we suggest working virtually with a large monitor or two screens. This setup allows you to follow along on Zoom while also doing the hands-on coding.
Please click here for details about using Zoom.
Zoom + Working Virtually
- Please be aware that there is the option to use closed captioning:

Assignments
Grading
All assignments are due June 28th at 11:59pm ET.
| Assignment | Percent of Grade |
|---|---|
| Attendance/Participation | 20% |
| Homework 1 | 15% |
| Homework 2 | 15% |
| Homework 3 | 15% |
| Final Project | 35% |
| Total | 100% |
Note: only people taking the course for credit must turn in the assignments. However, we will evaluate all submitted assignments in case others would like feedback on their work.
Homework
You should complete the following:
| Module | Details | Code |
|---|---|---|
| Homework 1 | Day 0 Instructions | HTML |
| Homework 2 | Rmd, HTML, Key, Key HTML | |
| Homework 3 | Rmd, HTML, Key, Key HTML |
Final Project
This project should entail:
- reading in a dataset of your choosing
- doing some light data cleaning
- performing some data summarization
- creating a couple of visualizations
- doing some very light statistical analysis, like regression or t-tests
You may use public datasets, or your own data for the project. If using your own dataset, be sure any sensitive information is protected.
Example projects can be found with the source code: Rmd, and the output html here.
See the guidelines/instructions for final projects, including dataset resources.
Submission
All assignments are due June 28th at 11:59pm ET.
Submit each assignment to the designated Drop Box on CoursePlus.
Assignment Extensions
We know that you will try your best to submit assignments on time. However, we understand that life happens. We can accept late assignments with a deduction of 2% of your assignment score per day late.
For example, if you scored 9/10 on an assignment (90%) but turned it in two days late, your score would be 8.6/10 (86%).
Code of Conduct
We would like to create an open, safe, welcoming, diverse, inclusive, intellectually stimulating, and hopefully fun class experience.
We strive to be a space in which individual differences are respected, so that each individual can reach their fullest potential.

- Avoiding making assumptions about others
- Being respectful of differing opinions, viewpoints, and
experiences
- Take the time to consider how your speech and actions may influence
others
- Actively seek to acknowledge and respect the boundaries of other
members
- Demonstrating academic integrity
- Students can work together, but assignments must show unique
contributions from the student who turns in the assignment
- Students can use online resources for help, but assignments must
show unique contributions from the student who turns in the assignment -
plagiarism is not allowed
- If students are struggling, reach out to instructors or TAs as early as possible
- Students can work together, but assignments must show unique
contributions from the student who turns in the assignment
This applies to emails, surveys, Slack, Zoom, office hours, meetings with other students, instructors, or TAs.
Please reach out to a TA or instructor if you witness or experience a violation of the class guidelines or other JHU codes of conduct.
