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.
