What software are you using, exactly? I'm the maintainer of the randomForest package, yet I do not know which "manual" you are quoting.
If you are using the randomForest package, the model object can be saved to a file by save(Rfobject, file="myRFobject.rda"). If you need that to be in ascii, use ascii=TRUE in save(). You can get it back into R by using load() or attach(). To "run data down the model", use predict(Rfobject, datatopredict) (see ?predict.randomForest). What exactly do you want to print to a csv file, the prediction? See ?write or ?write.table. Andy From: Jennifer Dawn Watts > > Hello!
