Preparing Data for Analysis
Where an inordinate amount of time is spent
Learning Path
Where we’ve been
Learning how to read our data and ask questions that are potentially answerable with this data.
Where we’re at
- Starting to write code.
- Recognizing that this stage will take time and that you are learning something challenging.
- Willing to ask for help and collaboration
Objectives
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:
- Set preferences for sanity (19.5)
- Install the
tidyverseandherepackages (19.6) - Create a R project using the
MATH615folder 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.
- Read through and follow the “Hello Quarto” tutorial (19.8 intro)
- Install the
tinytexprogram 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.
