The weights given should correspond to the ordering of levels(y) where y
contains the class labels. If in doubt, you can also give the classwt
as a named vector (e.g., classwt=c(B=3, A=2, C=1)).
Search in the R-help archive to see other options and why you probably
shouldn't use classwt.

6 levels { Great, Greater, Greatest, Weak, Weaker, Weakest}, and
predictor variables X, with continuous and factor variables using
random forests in R. The variable Y acts like an ordinal variable, but
I recoded it as fact
