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!

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?

I think you need to read those questions again more carefully... particularly the second one.

Hi Elahe,

Based on this and your other questions I think you could benefit from
spending time with tutorials on ggplot and on R in general.

Google should give you plenty and I quickly found this:
http://www.ats.ucla.edu/stat/r/ and this:
https://www.nceas.ucsb.edu/files/scicomp/Dloads/RProgramming/BestFirstRTutorial.pdf
R tutorial but others might suit your needs. For the ggplot tutorial I came
across http://tutorials.iq.harvard.edu/R/Rgraphics/Rgraphics.html and
http://www.r-bloggers.com/basic-introduction-to-ggplot2/

I have only skimmed the linked pages and it looks like a good starting
point.

Hope this helps
Ulrik
