Showing percentage instead of counts in a bar plot - ggplot2 - R

Question

I am working with the 'mtcars' dataset and have made this bar plot for the 'cyl' column:

For the y-axis, i want to see percentage instead of count. Is that possible?

Answer 1

Load the 'scales' package first, which gives different attributes to alter your scales.

library(scales)

Now, the below command is what you need:

ggplot(data = mtcars,aes(x=factor(cyl)))+geom_bar()+scale_y_continuous(labels=percent)
