Multivariate regression tree (mvpart)

Dear list members,

I am working with the mvpart package.
The plot for a multivariate tree give 2 numbers associated to each 
terminal node, one is the number of sampling units. Does anybody know 
what the other number mean?
Also, is there any other package that handle multivariate regression 
trees?
Thank you very much in advance.
Best,

Manuel

Dear Manuel,
This is the deviance of the node.

You can have an access to it by:

object$frame

As far as I know, there is no other multivariate regression tree package in
R.

All the best
Wilfried
