Key Concepts Learned
- Public Sector Data scinece has several considerations different from private sector
- Public good, and equity consideration
- Needs to be interpretable and not have algorithmic bias
- Git is for version control system (VCS)
- Github is the cloud computing backend of Git
- Github Lingo
- Folder -> Repo
- Commit -> Post a snapshot
- Push means to send files to cloud
- Pull downloads the files to local machine
- Setting up repositories on
- “YAML Ain’t Markup Language”
Coding Techniques
- Basics of tidyverse and its accompanying commands of filter(), select(), mutate(), and summarize()
- Quarto functions on how to bold, italics, both bold and italics,
code list, and strikethrough
- Quarto uses — as the header call
- “#” are used as the header calls
- Tibbles
- select() choose columns
- filter() choose rows
- mutate() create new variables
- summarize() calculate statistics
- group_by() operate on sub-groups
- Summarize and group_by tend ot happen together and typically using a pipeline %>%
- %>% pipelines are used to connect multiple codes in one command line rather than a sequence.
Questions & Challenges
- Everything was clear. I would still like to mess around more with Quarto.
- I messed around with Quarto again @ 9/14/2025
Connections to Policy
- This was a building block week, so not much of direct application rather tracking and documentation baseline for setup.
Reflection
- Learning how to create a custom repository was both enjoyable and insightful.
- It could also serve as a way to share supplementary analyses and to present code in a more public, graphical, and accessible format for non-coding audiences.
