Hi Duncan, Thanks for your reply. How do you know that (i) boxplot.stats lives in the grDevices namespace? and (ii) how do you know/change that boxplot will look in grDevices before it uses the local copy? I tried to do as you suggested and create a local copy of boxplot. I used the following commands: boxplot.stats <- edit(boxplot.stats) # Made changes to line 14 boxplot <- edit(boxplot) boxplot.default <- edit(boxplot.default) # Added a call to "cat()" When I called boxplot() the local copy was executed (as I could see the output of my "cat" commands), however it appears that the local copy of boxplot.stats isn't the one being called from my version of "boxplot". How do I fix this?
