1. (1 p) Concatenate HW01, HW02, and HW03 with appropriate sections and table of contents.

  2. (1 p) Data subset (from WS 05).

  3. (1 p) Rename variables (from WS 05).

  4. (3 p) Code missing variables, remove records with missing values, indicate with R output that this was done correctly (e.g., str(), dim(), summary()).

  5. (1 p) Label variables and label levels of factor variables.

  6. (1 p) Numerical summaries of all variables (from WS 05).

  7. (2 p) Graphical plots of at least one categorical and at least one numerical variable (from WS 06).

Starting at HW03, we will concatenate all our HWs together to retain the relevant information needed for subsequent sections. You will also have an opportunity to revisit previous parts to make changes or improvements, such as updating your codebook, modifying your research questions, improving tables and plots. Please organize your headers using the # symbol appropriately, and generate a table of contents by using the “toc: true” in the yaml (see any previous Rmd file on the website).
