Hi, I'm trying to graph some data in a boxplot-like style, but I want to set the box and whisker limits myself (rather than having R calculate them for me). I'd like the boxes to be shaded and the whiskers to be dotted lines. My data are set up is something like this: min.whisker max.whisker min.box max.box species 0 200 20 37 A 0 150 0 10 B 10 55 12 20 B etc... I have a categorical variable (species) which I'd like to use to group the boxes along the x-axis of the graph. I tried to do this by plotting a blank graph and adding the boxes and lines individually using the lines() function, but it was labour intensive, inelegant, and I couldn't get the bars in each group (species) not to overlap with one another. Does anyone know how to accomplish a graph like this in R with more succinct coding and/or a custom graphing package? Thanks! Regards, Brianna [[alternative HTML version deleted]]

(You just have to add the median to what you have provided in your example.)
