Warning in `geom_col()` when panel has 0 rows

[teunbrand]

This is a slightly contrived example, but the bar's width calculation can be chatty when there is a factor level in the PANEL that has 0 rows in the data.

library(ggplot2)

df <- mpg
df$drv <- factor(df$drv, c("4", "f", "r"))

ggplot(subset(df, drv != "4"), aes(cyl, cty)) +
  geom_col() +
  facet_wrap(~ drv, drop = FALSE)
#> Warning in min(x): no non-missing arguments to min; returning Inf
#> Warning in max(x): no non-missing arguments to max; returning -Inf
#> Warning in min(d[d > tolerance]): no non-missing arguments to min; returning
#> Inf
