Does this example help?
my.values <- c(10, 5)
err1 <- c(.5,.3)
x <- barplot(my.values, ylim=c(0,12))
arrows(x,my.values-.5 ,x,my.values+.5, code=3, angle=90, length=.1)
box()

I would like to add error bars to a bar chart, I have created in R. I am able
to add error bars to a bar plot, but the same method does not seem to work
for my bar chart version.
Â
Is there a way to add error bars to bar charts?
