Week 1 Readings

Introduction to R/RStudio/Vectors

Required

Remember, this reading is mostly supplemental and will help you if there are concepts that are unclear in class.

• R and RStudio Basics (Chapter 3) - make sure to watch the videos.
  • Skip the following sections in Chapter 3:
    • 3.3.1, 3.3.3,
• Intro to R & Rstudio, and Quarto from Day 1 of BSTA 511/611 in Fall 2023 (taught by Meike Niederhausen)
• Vectors and Data Frames (Section 3.3)
• Workflow: scripts and projects
  • Section 6.1: Scripts
  • Section 6.2: Projects

Optional

Posit/R Cheatsheets

• Many useful information and tips can be found in the list of cheatsheets on the Posit website

Markdown Basics

• This is a short reference on how to do formatting in Markdown. This is optional, but may be a helpful reference as you continue on and work with Markdown and Quarto.
  • https://sph-r-programming-2023.netlify.app/reference/markdown.html
  • Most of these topics are covered above in the Day 1 notes of BSTA 511/611.
  • Skip the last two sections on Front matter and Citations, since these are different for Quarto.
    • A similar resource for Quarto specifically
    • Quarto YAML for html
    • Quarto front matter

Swirl Basics

I’m going to highlight another resource for learning basic R concepts: swirl. This is a software package for R.

To start it, run the following code in the console in RStudio Cloud:

library(swirl)
swirl()

You’ll want to take a look at the R Programming course, especially the following sections:

1. Basic Building Blocks
2. Sequences of Numbers
3. Vectors
4. Missing values
