Adding error bars to a bar plot in R using calculated standard errors

Question

I created the barplot using two columns from a text file which also has a third column for standard errors. I used barplot() for this.

How do I add error bars using my column, se, from my text file?

I tried using error.bar() but that didn't work.

Thanks for the checkmark, but this answer is arguably a link-only answer and probably should have been deleted. – IRTFM Nov 14 '14 at 19:31
