Dear useRs, I very much like the effect display of the proportional odds model on page 29 (Figure 8) of the following paper by John Fox: http://socserv.mcmaster.ca/jfox/Papers/logit-effect-displays.pdf It really gives a very concise overview of the model. I would like to use it to illustrate the proportional odds mixed models we fit here for a project on Diabetes but I can't seem to reproduce the plot. Does anyone have code for the plot? Maybe John Fox himself? I would appreciate it very much.

Looks like there is code in the appendix.

Dear Jan, First, I inadvertently removed material on these displays from my web site when the paper was published in Sociological Methodology 2006. I'll update and repost the material some time in the next couple of days, including a copy of the published paper (with a link on my home page). Second, the appendix to the paper and the originally posted examples didn't include the code for Figure 8 (which is Figure 10 in the published version of the paper). I'll add that.

Dear Jan, I've placed a copy of the published version of the paper at <http://socserv.socsci.mcmaster.ca/jfox/Misc/polytomous-effect-displays/inde x.html>, along with the R code for computing effects and their standard errors and R code for the graphs in the paper. As you'll see, the functions provided do not construct graphs automatically, as those in the effects package do for linear and generalized linear models. Eventually, I'd like to incorporate this material in the effects package.
