如何在不加载包的情况下使用`ggplot2`的功能？

Question

When using ggplot2 , sometimes we need to use multiple functions in order to plot data:

library("ggplot2")
p <- ggplot(mpg) + 
  geom_bar(aes(x = .data$drv)) + 
  coord_flip()

An alternative way to do this plot without loading the whole ggplot2 package would be:

p <-ggplot2::ggplot(ggplot2::mpg) + 
   ggplot2::geom_bar(ggplot2::aes(x = .data$drv)) + 
   ggplot2::coord_flip()

How can we do this plot without having to load the package throught library("ggplot2") , or having to write ggplot2:: for every function?

Answer 1

withr::with_package temporarily loads a package.

p <- withr::with_package("ggplot2", {
  ggplot(mpg) + 
    geom_bar(aes(x = drv)) + 
    coord_flip()
})
