label_* functions do not appear to work within aes()

[py9mrg]

Hello,

I've just noticed that the new label_* versions do not seem compatible with being used inside aes(). Compare:

library(ggplot2)

ggplot(mtcars, aes(cyl, mpg)) +
  geom_point() +
  geom_text(aes(label = scales::comma(disp*1000)), vjust = 1, hjust = 1)

which works fine, with

library(ggplot2)
ggplot(mtcars, aes(cyl, mpg)) +
  geom_point() +
  geom_text(aes(label = scales::label_comma(disp*1000)), vjust = 1, hjust = 1)

Dont know how to automatically pick scale for object of type <function>. Defaulting to continuous.
Error in `geom_text()`:
! Problem while computing aesthetics.
ℹ Error occurred in the 2nd layer.
Caused by error in `compute_aesthetics()`:
! Aesthetics are not valid data columns.
✖ The following aesthetics are invalid:
✖ `label = scales::label_comma(disp * 1000)`
ℹ Did you mistype the name of a data column or forget to add `after_stat()`?
Run `rlang::last_trace()` to see where the error occurred.

The function with the label_-prefix are function factories. If you want to use them as regular functions, you can use label_comma()(disp * 1000) for example. Though in this particular case, you could also use label_comma(scale = 1000)(disp).

@teunbrand ugh - of course I can. Total brainfreeze, sorry - thank you for your patience!
