Dear Colleagues, I think the allure of bargraph.CI is that it makes it easy to plot standard errors--though you still have to fiddle with the options to get the size of confidence interval you want. And there is the (strong) dislike of dynamite plots by some (the ink to info argument).
Box and whisker plots have such a tradition of meaning in the boxes and whiskers that to add standard errors requires some additional work and explanation, and even then standard error markings are easily lost among the usual box and whisker plot markings. I have looked only briefly at tplot(), but don't recall seeing an easy way to add standard errors. Have I missed it? Would it be an easy add? A bad idea?
