I think you are right. In trying out various R code examples that make use of Design's nomogram() function (even in the help file for this command), there seems to be difficulty in actually making the graph look good. There are problems in relative size of the scales in terms of readability, problems in size of variable labels, problems in the size of the optimal graphics device aspect ratio, etc. That said, when the graph looks good, it is an outstanding graphic device for presenting a fitted model to a non-statistician. But, as you say, it is not an easy program to knock off, and it is questionable how useful it really is. Cool, but enough so to replace or complement estout?

You would have to want to be able to use it, very much. I would be

pleased to be shown wrong on that first impression.

I followed this link too, and while it is a nomogram (Fagan's

nomogram) it is not what I'm after. Nomogram() in R is more general

and follows any GLM. See the example picture in the first link I gave.

Just about every other week I drop into our R clinic for a coffee

break to listen to people's questions and maybe ask one myself. The

clinic is about general use questions, not especially about

Bioconductor packages, which is one reason to use R. The clinic is run

by a very capable R expert. Originally I started going to the clinic

thinking to myself that well, maybe this would be the last version of

Stata I would buy, because R has come miles in development and

documentation. More often than not, however, I conclude the opposite,

and continue to regularly use Stata, thinking there is value is good

commercial products.

One interesting function in R that I can't find in Stata is Frank

Harrell's nomogram function in the Design package, which essentially

is a graphical alternative to outreg or estout.
