R help - Sep 2016 - ggplot grouped barchart based on marginal proportions

Hi Paul,

Do you want to avoid using prop.table(mtcars_xtab, 1) ?

If not, how about:

ggplot(as.data.frame(prop.table(mtcars_xtab, 1)))+
 geom_bar(aes(x=Var2,y=Freq,fill=Var1), stat="identity",
position="dodge")+
 scale_fill_brewer(palette="Set2")


Ron.
