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.
