R help - Jun 2016 - duplicate labels in Bar chart geom_text()

Hi all,
how should I avoid duplicate labels in geom_text for bar chart? in the bar chart
below I have name of one country repeated several times on my bars, I only want
COUNTRY to be shown above each bar:

   
ggplot(df,aes(factor(Variable1),y=Variable2,fill=Variable3))+geom_bar(stat='identity')+geom_text(paste0(df$COUNTRY),position=position_dodge(width=0.2))

Thanks for any help!
