Hi All,

I am looking for a reference that explains how the randomForest function in
the randomForest package uses the classwt parameter. Here:

http://tolstoy.newcastle.edu.au/R/e4/help/08/05/12088.html

Andy Liaw suggests not using classwt. And according to:

http://r.789695.n4.nabble.com/R-help-with-RandomForest-classwt-option-td817149.html

it has "not been implemented" as of 2007. However it improved classification
performance for a problem I am working on, more than adjusting the sampsize
parameter. So I'm wondering if it has been implemented recently (since 2007)
or if there is a detailed explanation of what this unimplemented version is
doing.

Thanks!
James
