[R] Package for Multiple Additive Regression Trees

[Christopher Schwalm]

Hello List,

I've been unsuccessful in tracking down a package that does MART. J 
Friedman's website has a page that mentions an R implementation but the 
links lead nowhere. There is also a nice walkthru/vignette pdf on his site. 
But I can not find this package anywhere. Perhaps it's commercial? Does 
anyone know of where it might be available or of any other R package (or 
Matlab toolbox) that can do MART?

Many thanks,
Christopher
