[R] Effect display of proportional odds model

[John Fox]

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.

Regards,
 John

> 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.
