Show percent % instead of counts in charts of categorical variables

I\'m plotting a categorical variable and instead of showing the counts for each category value.

I\'m looking for a way to get ggplot to display the perc

If you want percentage labels but actual Ns on the y axis, try this:

    library(scales)
perbar=function(xx){
      q=ggplot(data=data.frame(xx),aes(x=xx))+
      geom_bar(aes(y = (..count..)),fill="orange")
       q=q+    geom_text(aes(y = (..count..),label = scales::percent((..count..)/sum(..count..))), stat="bin",colour="darkgreen") 
      q
    }
    perbar(mtcars$disp)
