This is a web-based tutorial that I use as my first assignment which the students do in class so they can get help. Note that there are some deliberate mistakes to show students how to troubleshoot.
Start with Worksheet 3 (qmd) which requires no additional files. Download it and open it in R Studio and click Render.
Download both files in the Worksheet 4 folder and open the quarto (qmd) file in R Studio. The other file is an image file (jpg) that the quarto (qmd) file needs when rendering.
The Bar Charts folder has files for MAT 145: Data Visualization. The data file (csv) is needed to render each of the quarto files. One is the assignment that we worked on together in class and the other is the complete version.
