Plotting an interaction with error bars

Thank you Jim.

brkdn.plot() seems to be just the function I need.

Still, I wonder if there are lists of labels of the different measures
of central tendency (mct argument) and measures of dispersion (md)?

   

Hi Dror,
With brkdn.plot (and several other functions in plotrix) you can use any 
existing measure or even roll your own. The only limitation is that the 
function has to return a numeric value and must accept an "na.rm" argument.
