Dear r-helpers, An editor has suggested that I use bar plots to capture an interaction of two 2-level factors and an interaction of a 2 by 3 factorial experiment. (It would seem that there's a fear that someone might try to interpolate between, e.g., 'male' and 'female'.) In general it seems to me that an interaction plot with lines is easier to read, and not likely to mislead. Does anyone know if and where this has been discussed? _____________________________ Professor Michael Kubovy University of Virginia Department of Psychology USPS: P.O.Box 400400 Charlottesville, VA 22904-4400 Parcels: Room 102 Gilmer Hall McCormick Road Charlottesville, VA 22903 Office: B011 +1-434-982-4729 Lab: B019 +1-434-982-4751 Fax: +1-434-982-4766 WWW: http://www.people.virginia.edu/~mk9y/

I have never seen anything else than lines for such a plot. However, I once was successful in using somewhat wider lines that looked barish. Which made me believe that the "paid by the ink" is not too bad an analogy: editors fear graphics that look too empty, so give them their black. I am sure Hadley will argue that this is the reason why ggplot2 by default has a gray background.
