How do I identify what a default element of a ggplot2 theme is?

In particular, I am interested in axis.ticks.length.

iris %>% 
  ggplot() +
  geom_point(aes(Sepal.Width, Sepal.Length)) 

iris %>% 
  ggplot() +
  geom_point(aes(Sepal.Width, Sepal.Length)) +
  theme(axis.ticks.length = unit(1, "lines"))

Created on 2023-06-20 with reprex v2.0.2

So the question I have is: how long are the default ticks in ggplot2 for theme_gray?

Hi @davidhodge931
You should be able to mine the output from this:


Many of the sizes are specified in relative units specified by the rel() function.
