Euro symbol in ggplot: package of weights

I have noticed that using a package scales, you can display the dollars on the axis, using the parameter scales = dollarin, for example scale_y_log10(). It seems that there is no such option as scales = euro. Is there an easy way to achieve the same effect?

It is easy to change the value of the dollar and change the symbol to euro. Run this and put it in code, as you would calldollar_format

euro_format <- function(largest_with_cents = 100000) {
  function(x) {
    x <- round_any(x, 0.01)
    if (max(x, na.rm = TRUE) < largest_with_cents &
        !all(x == floor(x), na.rm = TRUE)) {
      nsmall <- 2L
    } else {
      x <- round_any(x, 1)
      nsmall <- 0L
    }
    str_c("€", format(x, nsmall = nsmall, trim = TRUE, big.mark = ",", scientific = FALSE, digits=1L))
  }
}

You can use arguments prefixandsuffix dollar_format

For example, for example:

library(ggplot2)
library(scales)       
ggplot(diamonds) + geom_point(aes(x = carat, y =  price)) + scale_y_continuous(labels = dollar_format(suffix = "€", prefix = ""))
