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
