How to avoid warnings when adding a secondary axis without breaks or labels in ggplot2 3.5.0?

[IndrajeetPatil]

Prior to this release, I could use the secondary axis only to display an additional label, and not include breaks or labels. To do so, I could do the following, but, as can be seen, warnings are generated, and I would like to avoid these warnings since the users of my package will also see these warnings.

library(ggplot2)

ggplot(mtcars, aes(wt, mpg)) +
  geom_point() +
  scale_y_continuous(sec.axis = dup_axis(name = "my secondary axis", breaks = NULL)) 
#> Warning in min(x): no non-missing arguments to min; returning Inf
#> Warning in max(x): no non-missing arguments to max; returning -Inf

ggplot(mtcars, aes(wt, mpg)) +
  geom_point() +
  scale_y_continuous(sec.axis = sec_axis(transform = I, name = "my secondary axis", breaks = NULL)) 
#> Warning in min(x): no non-missing arguments to min; returning Inf

#> Warning in min(x): no non-missing arguments to max; returning -Inf

Thanks for the report! This seems like a regression that should be fixed in ggplot2
