Profiling Performance

Thomas Lin Pedersen

In order to continuously monitor the performance of ggplot2 the following piece of code is used to generate a profile and inspect it:

library(ggplot2)
library(profvis)

p <- ggplot(mtcars, aes(x = mpg, y = disp)) + 
  geom_point() + 
  facet_grid(gear ~ cyl)

profile <- profvis(for (i in seq_len(100)) ggplotGrob(p))
