add value to Bar chart ggplot2

Thanks Ulrik,
But in these examples they want to mark the percentage or frequency of plot variables, in my case I want to mark the bars with a different variable of my df. DO you have any idea?

Hi Elahe,

maybe this will help: http://stackoverflow.com/questions/6455088/how-to-put-labels-over-geom-bar-in-r-with-ggplot2 or this: http://stackoverflow.com/questions/12018499/how-to-put-labels-over-geom-bar-for-each-bar-in-r-with-ggplot2

Best,
Ulrik

Hi all ,
I have the following bar chart and I want to add SLC variable values to the charts but I don't know how to use geom_text:


   ggplot(df,(Protocol,fill=quant))+geom_bar()+coord_flip()

Thanks for any help!
Elahe
