I googled it and did not find the paper on it. Could you give me a link, please?

I get different order of importance for my variables depending on their order in the training data. Is there a parameter I could fiddle with (e.g. ntree) to get a more stable importance order? And finally, since interactions are not implemented, is there another method I could use in R to find dependencies among categorical variables? (lm doesn't accept categorical variables).
