I don't know much about sunflowerplots, but perhaps hexagonal binning might make be worth a look in your case if you are generally looking for a scatterplot but the point density is too high.
http://cran.r-project.org/web/packages/hexbin/index.html Take a look at the vignettes. You can also hexbin in ggplot2: http://had.co.nz/ggplot2/stat_binhex.html Hope this helps, Michael On Tue, Mar 13, 2012 at 5:59 PM, Henry <[email protected]> wrote: > I'm having a bit of trouble finding and understanding the correct function to > make numeric vectors to feed the sunflowerplot function.
