Hello everyone!
I need to include the confidence interval bar in a grouped barplot. I've
found some options on the web, but none of them solved my problem.
The question is: my barplot was created using vectors for each pair of bar
and them combining them using cbind.
I mean:
a=c(10,15)
b=c(20,24)
c=c(21,23) ...
hei=cbind(a,b,c)
graph1=barplot(hei, beside=T,...)
I've tried to include each CI in a vector just like the height of the bars,
but it hasn't worked (!!)
Is there an easy way to do this??
Thanks a lot =)
