In yutannihilation/gridutils: Small Utilities For grid Package

gridutils

This package is just my personal practice to play with grid.

Installation

# install.packages("devtools")
devtools::install_github("yutannihilation/gridutils")

Usages

gu_you_are_here()

Highlight the current viewport. Unlike grid::showViewport(), the highlight is removed after a while.

gu_you_are_here()

gu_print_vp()

library(gridutils)

library(ggplot2)
library(grid)

p <- ggplot(mtcars, aes(wt, mpg))
p + geom_point() + facet_wrap(~ cyl)
