Dear list For my work, it would be helpful if rpart worked seamlessly with an empty model: library(rpart); rpart(formula=y~0, data=data.frame(y=factor(1:10))) Currently, an unrelated error (originating from na.rpart) is thrown. At some point in the near future, I'd like to release a package to CRAN which uses rpart and relies on that functionality. I have prepared a patch (minor modifications at three places, and a test) which I'd like to propose for inclusion in the next CRAN release of rpart. The patch can be reviewed athttps://github.com/krlmlr/rpart/tree/empty-model, the files (based on the current CRAN release 4.1-8) can be downloaded from https://github.com/krlmlr/rpart/archive/empty-model.zip. Thanks for your attention. With kindest regards Kirill M?ller
In general I try to make functions behave in edge cases, so am symptatheic to your request. But I won't get to it for months at least, even if I say yes. Brian Ripley is the official maintainer of rpart at this time, send a note directly to him. If neither Brian nor I can fit it in, no one else will.
