Your Turn

Working in exercises.Rmd:

  • Fix the code in R/themes.R to use ggplot2:: instead of library(ggplot2)

  • Run use_package(“ggplot2”) to add ggplot2 to Imports

  • Re-load the package (Cmd/Ctrl+Shift+L) and run this code to make sure it works

use_package("ggplot2")

### in R/themes.R:

theme_avalanche <- function() { 
     ggplot2::theme_minimal(base_size = 14) + 
     ggplot2::theme(panel.grid.minor = ggplot2::element_blank())
}
