This document provides a running list of all packages and functions introduced in the DataCamp lecture slides. It will only include the functions explicitly shown in the slides. Therefore, it excludes functions discussed only in the interactive interface.

I will try to update it each Tuesday, just before class. If I forget, please email me.

To get additional information:

learn about a package by typing help(package = "PACKAGE_NAME") into the R console.
find package tutorials by typing browseVignettes(package = "PACKAGE_NAME")
learn about a function by typing ??function_name (two question marks) into the R console.
- if you already have the package loaded into memory, you can just type ?function_name (one question mark)
- or, if you know the name of the package, you can type ?package_name::function_name
- or you can search for the function at rdocumentation.org
