I haven't tried changing the mtry or ntree at all ... though I suppose with
only 6 variables, and tens-of-thousands of rows, we can probably do less
than 500 tree's (the default?).
Although tossing the forest does speed things up a bit, seems to be about 15
- 20% faster in some cases, I need to keep the forest to do the prediction,
otherwise, it complains that there is no forest component in the object.
