You should provide raw data to boxplot(), not summary stats. If you want to input summary stats, there was a post some time ago on that: http://finzi.psych.upenn.edu/Rhelp10/2010-September/251674.html <\quoate>
Overwriting $stats did the job for me. I wanted to show the effect of using different quantile computation methods. Thanks a lot to everybody for the quick answers!
