Loading Packages in R

• install.packages("Package_name") to install a package.
  • Before 1st use, but only once
  • Packages you need may already be installed
• library(Package_name) to load a package.
  • In general, do this at start of session
• Alternatively: ggplot2::ggplot().
  • “ggplot2” = package, “ggplot()” = function

library(tidyverse)
