R Introduction

Conventions

• All code is in monospace font text

• R functions end with parentheses: function()

• Directory names end with slash: home/

• Package names are surrounded by curly braces: {tidyverse}

• Keyboard buttons separate keys with a plus: Ctrl+S

• These are parentheses (), brackets [], and braces {}

• Links are in light blue text
