I cannot seem to write a randomforest model in PMML - either through calling PMML(model) or through Rattle. It appears that it is not yet supported. Randomsurvivalforest is, but not randomforest. Any ideas on possible workarounds for this? Thanks ncs

Thanks for the feedback. In the meantime, is there any other way to utilize the model outside of R, even if it is a little more complicated? ----- Original Message ---- From: Graham Williams <Graham.Williams at togaware.com> To: NCS <nc1963...

What does a status value of -3 mean when I do a regression with RF and use the getTree function? left daughter right daughter split var split point status prediction 1 2 3 11 4.721000e+03 -3 15.8489576...

I installed RF on Linux OpenSuSe 11.1 and while it did install and did run a model I had created on Windows correctly, it gave me a lot of "uninitialized" warnings. I don't know if these are significant...

Not the entire tree - I just selected a few rows. On the first tree, the only status codes I saw were -1 and -3, which makes sense. I am guessing the final tree should never have a status of -2...
