Sorry for the repost, but I've really been looking, and can't find any
syntax direction on this issue...

Just browsing the documentation, and searching the list came up short... I
have some unbalanced data and was wondering if, in a "0" v "1"
classification forest, some combo of these options might yield better
predictions when the proportion of one class is low (less than 10% in a
sample of 2,000 observations).

Not sure how to specify these terms... from the docs, we have:

classwt: Priors of the classes. Need not add up to one. Ignored for
regression.

So is this something like "... classwt=c(.90,.10)" ? I didn't see the syntax
demonstrated. Similar for "strata" and "sampsize" though there is a default
for sampsize that makes sense... not sure how you would make "a vector of
the length the number of strata", however....

Pointers?
