Yes, I am interested in tree-building algorithms that consider some (linear) combination of the covariates during the splitting. Sorry if I have not been clear enough.
There seem to be a large variety of methods (e.g. see http://www.tigr.org/~salzberg/murthy_thesis/survey/node11.html), I hoped that some methods might have already been developed as R packages... Thanks for the suggestions.
