Followup: Re: [R] Interaction Plots in R

I think it would be extremely useful to have code for interaction
plots. This is something I missed when working with linear models on
R. But why not add it to the R-base?

Well, I'm not sure that it is ready for that. For example, it has no
protection against wrong parameter types and cannot extract factors from
a dataframe (as the S-Plus version does). Compatibility to the S-Plus
version should be checked thoroughly, as a matter of fact. Generally,
much polish is missing, and I will probably not have the time to finish
it properly. Anybody who wants to do it is most welcome!

Meanwhile, if Ko-Kang Wang makes a package of it, that's enough for my
needs.
