Key Concepts Learned

  • [Basic Commands in R, what they do, and some grammar on them]

    -Group by and summarize go together very well, group by one column and then summarize the data in another column after selecting the groups using the first column. -%>% to pipe code together]

Coding Techniques

  • select() - choose columns • filter() - choose rows • mutate() - create new variables • summarize() - calculate statistics • group_by() - operate on groups

Questions & Challenges

  • [What I didn’t fully understand]
  • [I need more practice with the github interface.]

Connections to Policy

  • [We will use these technical concepts to manipulate data, and those inferences will be connected to policy content.]

Reflection

  • [Most interesting was learning how the github portfolio website operates, and how we can periodically change it.]
  • [I assume that as the semester progresses we will use this website to display our body of work]
