Week 12 - Data wrangling with dplyr

Introduction

Learning Objectives

1. Learners can apply ten functions from the dplyr R Package to generate a subset of data for use in a table or plot

Exercises

Exercise 1 - Application Exercise

1. Open the repo from class and pull changes from remote repository; A solutions file ae-12a-dplyr-solutions.qmd will be added; Ensure that your script ae-12a-dplyr.qmd is complete and renders without errors
2. Add, Commit, Push all changes to GitHub with the commit message “Render exercise 12a without errors”
3. Complete all tasks in Application Exercise 12 - Data wrangling with dplyr (ae-12b-dplyr.qmd file)
4. Ensure that ae-12b-dplyr.qmd renders without errors
5. Add, Commit, Push all changes to GitHub with the commit message “Complete tasks of exercise 12b”

Exercise 2 - Research Project Report

Continue to work on your research project report. The submission deadline is the 9th of June. Important: Review the list of graded items. Have you discussed within your group who is responsible for which of the items that are submitted by the team? Do you have open questions? If yes, submit issues on your team repo on GitHub.

1. Pull!
2. Keep refining your visualistions and write up your results.
3. Prepare at least two summary tables using functions of the dplyr R Package. 4 Open an issue on GitHub to let me know you have created summary tables for your report.
4. At the end of a work session, always make sure that your Git pane is empty and all changes are committed and pushed back to GitHub.

Exercise 4 - R4DS section on data transformation

If you want to practice more, then use your notebook from week 10 and work through the Chapter on Data transformation in R4DS: https://r4ds.had.co.nz/transform.html

Note: If you use the notebook to take notes while working through R4DS, then use the Render, Add, Commit, Push workflow every now and then to push your changes back to GitHub and keep your remote repository in sync with your local repository.
