Oblique decision tree using mvpart

First, thanks for your answer.
I find the description of mvpart package quite short:

"Wrapper function for fitting and plotting rpart models "

Then, I thought that mvpart was the package which seems closest to what I
would like to do (i.e. oblique decision tree also named multivariate
decision tree). However, as you pointed out, it is the answer which is
multivariate in the mvpart package.

Thus, this is for multivariate *responses*, not for multivariate splits.

So, to your knowledge, there is no R package for multivariate splits (i.e.
oblique decision trees)?
