Hi R users, I have a question about adding uncertainty bars to stacked bar plots.
DF: year A B C Amin Amax Bmin Bmax Cmin Cmax 2009 40 45 15 30 61 23 56 14 17 2010 36 41 23 26 54 22 51 22 24 I use the code below: DF.refm = melt(subset(DF[,c(1:4)]),id.vars='year',variable_name='Legend') fig1 = ggplot(data=DF.refm, aes(x=year,y=value,fill=Legend))+ geom_bar(stat='identity',size=.5)+ theme_bw()+ xlab('Year')+ ylab('Percent (%)') print(fig1) But I don't know how to change it a little bit. For example, how to add the error bars on the plot, as is shown in the figure below? The error bar for variable A ranges from Amin to Amax, the same applies to variables B and C. Thanks for your help. ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
