You need to be _extremely_ careful when assigning levels of factors. Look at
this example:
R> x1 = factor(c("a", "b", "c"))
R> x2 = factor(c("a", "c", "c"))
R> x3 = x2
R> levels(x3) <- levels(x1)
R> x3
[1] a b b
Levels: a b c
I'll try to add more proofing in the code...

Hello,
I came across a problem when building a randomForest model. Maybe someone can
help me.
I have a training- and a testdataset with a discrete response and ten
predictors (numeric and factor variables). The two datasets are similar in
terms of number of predictor, name of
