ggplot2 log scale labels with different digits

Question

Is there a way to display labels as

0.01, 0.1, 1, 10, 100

instead of

0.01, 0.10, 1.00, 10.00, 100.00

i.e., truncating trailing zeros after the decimal?

x <- c(0.01, 0.1, 1, 10, 100)
scales::demo_log10(x)
scales::demo_log10(x, labels = scales::label_number())

Please provide enough code so others can better understand or reproduce the problem. — Community, Mar 08 '23 at 21:34

The label_number() function forwards the ... argument to the format() function. This mean that you use its drop0trailing argument to control whether 0s are printed after the decimal mark.

library(scales)
demo_log10(
  c(0.01, 0.1, 1, 10, 100),
  labels = label_number(drop0trailing = TRUE)
)
#> scale_x_log10(labels = label_number(drop0trailing = TRUE))
