How to use this website?

Labs

First, let’s learn how to use the available code for lab files.

Using Lab Files

The R code in this website is executable. Each of the lab files is a Quarto Markdwon or .qmd document.

If you have background in coding and are just looking for a piece of code, or if you want to browse the code, you can access the Labs section and click on the relevant lab. The relevant code can be copied and ran on R scrip, R markdown or Quarto markdown.

If you want to access the very .qmd documents to use and replicate the code, you should:

  1. Use the latest version of RStudio, at least Version: 2022.12.0+353 or later on your computer.

  2. Within RStudio, click on new file drop down menu and open a new Quarto Document (see the first figure), and name it.

  3. Once the .qmd document is opened, go to the source tab, erase the default code and paste the code from the corresponding lab file (from line 1 up to the final line). Then hit Render. You will see output in the Viewer menu.

  4. You can click Show in a new window to open rendered code in your local browser window (see the second figure for highlighted commands).

RStudio Interface

RStudio Interface 2

Repo

Lab files are within the labs folder in Github Repo.

Lab 1 and 2

These labs are not included as they don’t involve any data analysis.

Lab 3: Descriptive statistics

Use the file Lab3-Descriptive-Stats.qmd.

Lab 4: EFA and CFA

Use Lab4-EFA-and-CFA.qmd.

Lab 5: t-test

Use Lab5-t-test.qmd.

More to come

Further lab files are yet to be added.

Slides

Slides are made using revealjs on Quarto. There are three ways to use them:

  1. Use live: From Presentations, click the corresponding presentation. They can be displayed live simply by clicking on them and using the keyboard arrow keys.

  2. Save as pdf: Get to the corresponding presentation as explained above. This option only works with Google Chrome as explained here.

  3. The revealjs files: The original code files on Github Repo are inside the presentations folder.

The process of using them is similar as using any other .qmd documents explained above. Once they are opened in RStudio, the Present button from the Presentation tab can be used to open the presentation in the local browser - that can be presented from there.
