[R] Exhaustive CHAID package

[Michael Grant]

Dear R-Help:

>From multiple sources comparing methods of tree classification and tree regressions on various data sets, it seems that Exhaustive CHAID (distinct from CHAID), most commonly generates the most useful tree results and, in particular, is more effective than ctree or rpart which are implemented in R.  I see that CHAID, but not Exhaustive CHAID, is in the R-forge, and I write to ask if there are plans to create a package which employs the Exhaustive CHAID strategy.  Right now the best source I can find is in SPSS-IBM and I feel a bit disloyal to R using it.
