R help - Feb 2008 - Package for Multiple Additive Regression Trees

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

There has been a rough R-code implementation of MART some years ago on
Friedman's home page. Since then, MART is only available from Salford
Systems as part of their TreeNet software.

I asked Jerome Friedman about the R/MART interface, but he only guided
me to the Salford System Web page. Salford replied, but I never received
any R interface for their software from them.

TreeNet is a very interesting Data Mining applicatione. To try it out
you can easily receive a demo license from Salford -- without the R
interface, of course.
