What gave you the idea that mvpart was an implementation of oblique decision trees? It does not say so anywhere.
help file, there is an example of the mvpart function using the spider data set. However, when trying the example I do not obtain an oblique decision tree with separating rules such as p1+p2<5, but rather simple rules of the form p1>3. Is it normal?
Yes. As the task view that I pointed you previously explains An adaptation of rpart for multivariate responses is available in package mvpart. Thus, this is for multivariate *responses*, not for multivariate splits. Z
