Emerson, J. D. (1991) Graphical Display as an Aid to Analysis, in *Fundamentals of Exploratory Analysis of Variance* (eds D. C. Hoaglin, F. Mosteller and J. W. Tukey), John Wiley & Sons, Inc., Hoboken, NJ, USA. doi: 10.1002/9780470316832.ch8

There describes side-by-side plots of effects and residuals…

I think it's a nice idea for exploratory analysis, but don't know how to draw it..

(The usual side-by-side boxplot is good for one-way analysis but when it gets to two way, it's too complicated to see main effects and interactions…)

Does anyone know how?

Here's some example from the excellent book "A First Course in Design and Analysis of Experiments", which is available on web!!!

On the topic of visualising ANOVA output, how about this. See here for motivation: http://www.acase.org/rpruzek/anovagraphic.pdf And here for a very basic explanation of the various parts of the figure: http://dl.dropbox.com/u/382638/Brian-Danielak-granova.pdf and http://dl.dropbox.com/u/382638/DanielakGranovaRevision20110714.pdf

And see here for the `R`

package that made this figure (using `ggplot2`
