Changing the order of bars in a bar-plot - ggplot2 - R

Question

I am working with the 'mtcars' dataset and have made this bar-plot with ggplot2:

I would want to arrange the bars in ascending order of count. i.e this needs to be the order of the bars: (6,8,3,1,2,4).

Is there a way to modify it?

Answer 1

You can use the scale_x_discrete() function with the parameter 'limits' to reorder the bars:

ggplot(data = mtcars,aes(x=factor(carb)))+geom_bar()+scale_x_discrete(limits=c(6,8,3,1,2,4))

The above command will give you the desired result:
