Error bars can be used to **visualizeÂ standard deviations, standard errors or** confidence intervals (just don't forget to specify which measure the error bar in the graph represents). Beyond this, it's just any additional aesthetic styling that you want to tweak and you're good to go! This not-so-straightforward idea comes from the R Wiki Tips and is reproduced here as a worked-out example.
