Accept tidyverse tilde functions

[davidsjoberg]

It would be neat to be able to use the same "short" version of defining function as in purrr in ggplot2 as well.

---

Example would be to be able to write:

ggplot(mtcars, aes(drat, qsec)) + 
  geom_line() +
  scale_y_continuous(labels = ~format(., nsmall = 1))

Today you need to do like this:

ggplot(mtcars, aes(drat, qsec)) + 
  geom_line() +
  scale_y_continuous(labels = function(x) format(x, nsmall = 1))

Thanks! :)

Yes, I think all the arguments that accepts functions should accept tilde notation. It's just we don't have enough development bandwidth to do it. Pull requests are welcome!

This now works. Probably fixed by #4188.

library(ggplot2)

ggplot(mtcars, aes(drat, qsec)) + 
  geom_line() +
  scale_y_continuous(labels = ~format(., nsmall = 1))
