Dear gracious R community, I would like to produce charts of phytoplankton biomass changes through time. Each species has a line, and the biomass varies in mirror form along the line for each species along the X time axis. Here is an example of what I'd like to do: http://www.er.uqam.ca/nobel/r30240/Succession.jpg Any suggestions? Thanks David Bird UQAM, Montreal

(the polygon plotting function is likely to be of use and you might want to look at how violin plots are handled.) -- David David Winsemius, MD West Hartford, CT

One method is kiteChart in the plotrix package. Jim
