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?

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.
