This document provides a running list of all packages and functions introduced in the lecture slides. 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
