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.
