Here's an alternative suggestion - don't use bars, use dots. Bar plots with standard errors are sometime called dynamite plots (probably because they should be blown up). See http://biostat.mc.vanderbilt.edu/twiki/bin/view/Main/DynamitePlots and http://emdbolker.wikidot.com/blog:dynamite for some reasons not to use them and possible alternatives. I hope that package authors who provide methods to make these plots easy will reconsider.
