Objectives

Items

Know several questions to ask yourself when preparing data for analysis

Understand options for literate programming

Import your chosen data into your SPC

Create a reproducible workflow

Create a reproducible script file that imports the raw data, performs data management tasks, exports an analysis ready data set

Preparation

In Homework 00 you downloaded and installed R and R Studio, and used it to import a data file in Homework 01. There are a few more steps to take that will allow you to be best setup for using R to analyze data.

Follow the instructions in the Appendix of the Applied Stats Course Notes to do the following:

  1. Set preferences for sanity (19.5)
  2. Install the tidyverse and here packages (19.6)
  3. Create a R project using the MATH615 folder that you created in step 1. (ASCN 19.7)
    • Shut down R studio fully, navigate to your class folder, and open your project file (the cube) before you continue.
  4. Read through and follow the “Hello Quarto” tutorial (19.8 intro)
  5. Install the tinytex program so you can create PDFs from your Quarto document. This is required (19.8)

If you have difficulty with any of this, visit Community Coding, my office hours, or post in Discord.
