I'm trying to find some example in randomForest with categorical variables
but I haven't found anything. Do you know any example with both categorical
and numerical variables? Anyway I don't have any class labels yet. How could
I find clusters with randomForest?

I had a look at the documentation of the package apcluster. That's
interesting but do you have any example using it with both categorical and
numerical variables? I'd like to test it with a large dataset..
Thanks a lot!
